The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:1975-1 advisory.

  - An issue was discovered in the Linux kernel through 5.3.9. There is a use-after-free when aa_label_parse()     fails in aa_audit_rule_init() in security/apparmor/audit.c. (CVE-2019-18814)

  - In the Linux kernel 5.3.10, there is a use-after-free (read) in the perf_trace_lock_acquire function     (related to include/trace/events/lock.h). (CVE-2019-19769)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - A vulnerability was found in Linux Kernel where refcount leak in llcp_sock_bind() causing use-after-free     which might lead to privilege escalations. (CVE-2020-25670)

  - A vulnerability was found in Linux Kernel, where a refcount leak in llcp_sock_connect() causing use-after-     free which might lead to privilege escalations. (CVE-2020-25671)

  - A memory leak vulnerability was found in Linux kernel in llcp_sock_connect (CVE-2020-25672)

  - A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak     and eventually hanging-up the system. (CVE-2020-25673)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other     clients even though the sender has not yet successfully authenticated to the AP. This might be abused in     projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier     to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation     does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can     abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-     confidentiality protocol. (CVE-2020-26141)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process     them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26145)

  - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble     fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject     packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)

  - An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-     of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects     pointer types that do not define a ptr_limit. (CVE-2020-27170)

  - An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error     (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to     side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory,     aka CID-10d2bb2e6b1d. (CVE-2020-27171)

  - An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users     can cause a denial of service (host OS hang) via a high rate of events to dom0, aka CID-e99502f76271.
    (CVE-2020-27673)

  - A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the     ability to set extended attributes to panic the system, causing memory corruption or escalating     privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system     availability. (CVE-2020-27815)

  - An out-of-bounds (OOB) memory access flaw was found in x25_bind in net/x25/af_x25.c in the Linux kernel     version v5.12-rc5. A bounds check failure allows a local attacker with a user account on the system to     gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information.
    The highest threat from this vulnerability is to confidentiality, integrity, as well as system     availability. (CVE-2020-35519)

  - An issue was discovered in the Linux kernel before 5.8. arch/x86/kvm/svm/svm.c allows a     set_memory_region_test infinite loop for certain nested page faults, aka CID-e72436bc3a52.
    (CVE-2020-36310)

  - An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a     denial of service (soft lockup) by triggering destruction of a large SEV VM (which requires unregistering     many encrypted regions), aka CID-7be74942f184. (CVE-2020-36311)

  - An issue was discovered in the Linux kernel before 5.8.10. virt/kvm/kvm_main.c has a     kvm_io_bus_unregister_dev memory leak upon a kmalloc failure, aka CID-f65886606c2d. (CVE-2020-36312)

  - An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka     CID-5d069dbe8aaf. fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system     crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as     CVE-2021-28950. (CVE-2020-36322)

  - An out-of-bounds access flaw was found in the Linux kernel's implementation of the eBPF code verifier in     the way a user running the eBPF script calls dev_map_init_map or sock_map_alloc. This flaw allows a local     user to crash the system or possibly escalate their privileges. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system availability. (CVE-2021-20268)

  - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability. (CVE-2021-23134)

  - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI     subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the     pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)

  - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)

  - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a     Netlink message. (CVE-2021-27365)

  - An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the     netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of     changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior     of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931.
    (CVE-2021-28038)

  - An issue was discovered in the Linux kernel through 5.11.6. fastrpc_internal_invoke in     drivers/misc/fastrpc.c does not prevent user applications from sending kernel RPC messages, aka     CID-20c40794eb85. This is a related issue to CVE-2019-2308. (CVE-2021-28375)

  - rtw_wx_set_scan in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the Linux kernel through 5.11.6     allows writing beyond the end of the ->ssid[] array. NOTE: from the perspective of kernel.org releases,     CVE IDs are not normally used for drivers/staging/* (unfinished work); however, system integrators may     have situations in which a drivers/staging issue is relevant to their own customer base. (CVE-2021-28660)

  - The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use     uninitialized or stale values. This initialization went too far and may under certain conditions also     overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking     persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died,     leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable.
    XSA-365 was classified to affect versions back to at least 3.11. (CVE-2021-28688)

  - An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur     because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)

  - An issue was discovered in the Linux kernel through 5.11.8. The sound/soc/qcom/sdm845.c soundwire device     driver has a buffer overflow when an unexpected port ID number is encountered, aka CID-1c668e1c0a0f. (This     has been fixed in 5.12-rc4.) (CVE-2021-28952)

  - A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It     allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer     before a cloning operation, aka CID-dbcc7d57bffc. (CVE-2021-28964)

  - In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some     Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS     status in a PEBS record is mishandled, aka CID-d88d05a9e0b6. (CVE-2021-28971)

  - In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has     a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination, aka CID-cc7a0bb058b8. (CVE-2021-28972)

  - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the kernel context. This affects     arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)

  - An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification performed by the first operation is not correctly     accounted for when restricting subsequent operations. (CVE-2021-29155)

  - An issue was discovered in the Linux kernel through 5.11.10. drivers/net/ethernet/freescale/gianfar.c in     the Freescale Gianfar Ethernet driver allows attackers to cause a system crash because a negative fragment     size is calculated in situations involving an rx queue overrun when jumbo packets are used and NAPI is     enabled, aka CID-d8861bab48b6. (CVE-2021-29264)

  - An issue was discovered in the Linux kernel before 5.11.7. usbip_sockfd_store in     drivers/usb/usbip/stub_dev.c allows attackers to cause a denial of service (GPF) because the stub-up     sequence has race conditions during an update of the local and shared status, aka CID-9380afd6df70.
    (CVE-2021-29265)

  - An issue was discovered in the Linux kernel before 5.11.11. qrtr_recvmsg in net/qrtr/qrtr.c allows     attackers to obtain sensitive information from kernel memory because of a partially uninitialized data     structure, aka CID-50535249f624. (CVE-2021-29647)

  - An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to     cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h     lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.
    (CVE-2021-29650)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI     controller. (CVE-2021-32399)

  - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an     hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)

  - kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic     operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel     memory, leading to local privilege escalation to root. In particular, there is a corner case where the off     reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.
    (CVE-2021-33200)

  - A flaw was found in the Linux kernel. A denial of service problem is identified if an extent tree is     corrupted in a crafted ext4 filesystem in fs/ext4/extents.c in ext4_es_cache_extent. Fabricating an     integer overflow, A local attacker with a special user privilege may cause a system crash problem which     can lead to an availability threat. (CVE-2021-3428)

  - The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when     the source register was known to be 0. A local attacker with the ability to load bpf programs could use     this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and     possibly out-of-bounds writes that could potentially lead to code execution. This issue was addressed in     the upstream kernel in commit 9b00f1b78809 (bpf: Fix truncation handling for mod32 dst reg wrt zero) and     in Linux stable kernels 5.11.2, 5.10.19, and 5.4.101. (CVE-2021-3444)

  - A flaw was found in the Nosy driver in the Linux kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality, integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected (CVE-2021-3483)

  - The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size     was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel     and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny     reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. It was introduced via 457f44363a88 (bpf: Implement BPF ring buffer and verifier     support for it) (v5.8-rc1). (CVE-2021-3489)

  - The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly     update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and     therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e (bpf: Fix alu32 const     subreg bound tracking on bitwise operations) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. The AND/OR issues were introduced by commit 3f50f132d840 (bpf: Verifier, do     explicit ALU32 bounds tracking) (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 (bpf:Fix a     verifier failure with xor) ( 5.10-rc1). (CVE-2021-3490)

  - The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the     PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.
    This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was     addressed via commit d1f82808877b (io_uring: truncate lengths larger than MAX_RW_COUNT on provide     buffers) (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was     introduced in ddf0322db79c (io_uring: add IORING_OP_PROVIDE_BUFFERS) (v5.7-rc1). (CVE-2021-3491)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2689 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that may lead to the execution of     arbitrary code, privilege escalation, denial of service, or information leaks. This update is not yet     available for the armel (ARM EABI soft-float) architecture. CVE-2020-24586, CVE-2020-24587, CVE-2020-26147     Mathy Vanhoef discovered that many Wi-Fi implementations, including Linux's mac80211, did not correctly     implement reassembly of fragmented packets. In some circumstances, an attacker within range of a network     could exploit these flaws to forge arbitrary packets and/or to access sensitive data on that network.
    CVE-2020-24588 Mathy Vanhoef discovered that most Wi-Fi implementations, including Linux's mac80211, did     not authenticate the is aggregated packet header flag. An attacker within range of a network could exploit     this to forge arbitrary packets on that network. CVE-2020-25670, CVE-2020-25671, CVE-2021-23134 kiyin     () of TenCent discovered several reference counting bugs in the NFC LLCP implementation which could     lead to use-after-free. A local user could exploit these for denial of service (crash or memory     corruption) or possibly for privilege escalation. Nadav Markus and Or Cohen of Palo Alto Networks     discovered that the original fixes for these introduced a new bug that could result in use-after-free and     double-free. This has also been fixed. CVE-2020-25672 kiyin () of TenCent discovered a memory leak     in the NFC LLCP implementation. A local user could exploit this for denial of service (memory exhaustion).
    CVE-2020-26139 Mathy Vanhoef discovered that a bug in some Wi-Fi implementations, including Linux's     mac80211. When operating in AP mode, they would forward EAPOL frames from one client to another while the     sender was not yet authenticated. An attacker within range of a network could use this for denial of     service or as an aid to exploiting other vulnerabilities. CVE-2020-26558, CVE-2021-0129 Researchers at     ANSSI discovered vulnerabilities in the Bluetooth Passkey authentication method, and in Linux's     implementation of it. An attacker within range of two Bluetooth devices while they pair using Passkey     authentication could exploit this to obtain the shared secret (Passkey) and then impersonate either of the     devices to each other. CVE-2020-29374 Jann Horn of Google reported a flaw in Linux's virtual memory     management. A parent and child process initially share all their memory, but when either writes to a     shared page, the page is duplicated and unshared (copy-on-write). However, in case an operation such as     vmsplice() required the kernel to take an additional reference to a shared page, and a copy-on-write     occurs during this operation, the kernel might have accessed the wrong process's memory. For some     programs, this could lead to an information leak or data corruption. CVE-2020-36322, CVE-2021-28950 The     syzbot tool found that the FUSE (filesystem-in-user-space) implementation did not correctly handle a FUSE     server returning invalid attributes for a file. A local user permitted to run a FUSE server could use this     to cause a denial of service (crash). The original fix for this introduced a different potential denial of     service (infinite loop in kernel space), which has also been fixed. CVE-2021-3428 Wolfgang Frisch reported     a potential integer overflow in the ext4 filesystem driver. A user permitted to mount arbitrary filesystem     images could use this to cause a denial of service (crash). CVE-2021-3483  (Zheyu Ma) reported a     bug in the nosy driver for TI PCILynx FireWire controllers, which could lead to list corruption and a use-     after-free. On a system that uses this driver, local users granted access to /dev/nosy could exploit this     to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.
    CVE-2021-3564, CVE-2021-3573, CVE-2021-32399 The BlockSec team discovered several race conditions in the     Bluetooth subsystem that could lead to a use-after-free or double-free. A local user could exploit these     to caue a denial of service (crash or memory corruption) or possibly for privilege escalation.
    CVE-2021-3587 Active Defense Lab of Venustech discovered a potential null pointer dereference in the NFC     LLCP implementation. A local user could use this to cause a denial of service (crash). CVE-2021-20292 It     was discovered that the TTM buffer allocation API used by GPU drivers did not handle allocation failures     in the way that most drivers expected, resulting in a double-free on failure. A local user on a system     using one of these drivers could possibly exploit this to cause a denial of service (crash or memory     corruption) or for privilege escalation. The API has been changed to match driver expectations.
    CVE-2021-23133 Or Cohen of Palo Alto Networks discovered a race condition in the SCTP implementation,     which can lead to list corruption. A local user could exploit this to cause a denial of service (crash or     memory corruption) or possibly for privilege escalation. CVE-2021-28660 It was discovered that the     rtl8188eu WiFi driver did not correctly limit the length of SSIDs copied into scan results. An attacker     within WiFi range could use this to cause a denial of service (crash or memory corruption) or possibly to     execute code on a vulnerable system. CVE-2021-28688 (XSA-371) It was discovered that the original fix for     CVE-2021-26930 (XSA-365) introduced a potential resource leak. A malicious guest could presumably exploit     this to cause a denial of service (resource exhaustion) within the host. CVE-2021-28964 Zygo Blaxell     reported a race condition in the Btrfs driver which can lead to an assertion failure. On systems using     Btrfs, a local user could exploit this to cause a denial of service (crash). CVE-2021-28971 Vince Weaver     reported a bug in the performance event handler for Intel PEBS. A workaround for a hardware bug on Intel     CPUs codenamed Haswell and earlier could lead to a null pointer dereference. On systems with the affected     CPUs, if users are permitted to access performance events, a local user may exploit this to cause a denial     of service (crash). By default, unprivileged users do not have access to performance events, which     mitigates this issue. This is controlled by the kernel.perf_event_paranoid sysctl. CVE-2021-29154 It was     discovered that the Extended BPF (eBPF) JIT compiler for x86_64 generated incorrect branch instructions in     some cases. On systems where eBPF JIT is enabled, users could exploit this to execute arbitrary code in     the kernel. By default, eBPF JIT is disabled, mitigating this issue. This is controlled by the     net.core.bpf_jit_enable sysctl. CVE-2021-29265 The syzbot tool found a race condition in the USB/IP host     (server) implementation which can lead to a null pointer dereference. On a system acting as a USB/IP host,     a client can exploit this to cause a denial of service (crash). CVE-2021-29647 The syzbot tool found an     information leak in the Qualcomm IPC Router (qrtr) implementation. This protocol is not enabled in     Debian's official kernel configurations. CVE-2021-29650 It was discovered that a data race in the     netfilter subsystem could lead to a null pointer dereference during replacement of a table. A local user     with CAP_NET_ADMIN capability in any user namespace could use this to cause a denial of service (crash).
    By default, unprivileged users cannot create user namespaces, which mitigates this issue. This is     controlled by the kernel.unprivileged_userns_clone sysctl. CVE-2021-30002 Arnd Bergmann and the syzbot     tool found a memory leak in the Video4Linux (v4l) subsystem. A local user permitted to access video     devices (by default, any member of the video group) could exploit this to cause a denial of service     (memory exhaustion). CVE-2021-31916 Dan Carpenter reported incorrect parameter validation in the device-     mapper (dm) subsystem, which could lead to a heap buffer overrun. However, only users with CAP_SYS_ADMIN     capability (i.e. root-equivalent) could trigger this bug, so it did not have any security impact in this     kernel version. CVE-2021-33034 The syzbot tool found a bug in the Bluetooth subsystem that could lead to a     use-after-free. A local user could use this to cause a denial of service (crash or memory corruption) or     possibly for privilege escalation.
