The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2103-1 advisory.

  - The acpi_ns_evaluate() function in drivers/acpi/acpica/nseval.c in the Linux kernel through 4.12.9 does     not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive     information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a     crafted ACPI table. (CVE-2017-13695)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and     unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c. (CVE-2019-19377)

  - An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.
    (CVE-2019-20811)

  - There is a flaw reported in the Linux kernel in versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue     results from the lack of validating the existence of an object prior to performing operations on the     object. An attacker with a local account with a root privilege, can leverage this vulnerability to     escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)

  - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

  - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

  - net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial     of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure     of a bind call. (CVE-2021-38208)

  - In bpf_prog_test_run_skb of test_run.c, there is a possible out of bounds read due to Incorrect Size     Value. This could lead to local information disclosure with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-154175781References: Upstream kernel (CVE-2021-39711)

  - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in     the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)

    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

  - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount     of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will     access the freed drm_vgem_gem_object. (CVE-2022-1419)

  - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols     functionality in the way a user terminates their session using a simulated Ethernet card and continued     usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)

  - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency     use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker     could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the     system. (CVE-2022-1652)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use     after free both read or write when non synchronized between cleanup routine and firmware download routine.
    (CVE-2022-1734)

  - A use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition     between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN     privilege to leak kernel information. (CVE-2022-1974)

  - There is a sleep-in-atomic bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by     simulating a nfc device from user-space. (CVE-2022-1975)

  - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated     user to potentially enable information disclosure via local access. (CVE-2022-21123)

  - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)

  - Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21127)

  - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)

  - Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially     cause a denial of service via local access. (CVE-2022-21180)

  - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

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

    Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation,     denial of service or information leaks. 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. This issue was already fixed for     most architectures, but not on MIPS and System z. This update corrects that. 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-2021-3640 Lin Ma discovered a race condiiton in the Bluetooth protocol implementation that can lead to     a use-after-free. A local user could exploit this to cause a denial of service (memory corruption or     crash) or possibly for privilege escalation. CVE-2021-3744, CVE-2021-3764 minihanshen reported bugs in the     ccp driver for AMD Cryptographic Coprocessors that could lead to a resource leak. On systems using this     driver, a local user could exploit this to cause a denial of service. CVE-2021-3752 Likang Luo of NSFOCUS     Security Team discovered a flaw in the Bluetooth L2CAP implementation that can lead to a user-after-free.
    A local user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-3760, CVE-2021-4202 Lin Ma discovered race conditions in the NCI (NFC     Controller Interface) driver, which could lead to a use-after-free. A local user could exploit this to     cause a denial of service (memory corruption or crash) or possibly for privilege escalation. This driver     is not enabled in Debian's official kernel configurations. CVE-2021-3772 A flaw was found in the SCTP     protocol implementation, which would allow a networked attacker to break an SCTP association. The attacker     would only need to know or guess the IP addresses and ports for the association. CVE-2021-4002 It was     discovered that hugetlbfs, the virtual filesystem used by applications to allocate huge pages in RAM, did     not flush the CPU's TLB in one case where it was necessary. In some circumstances a local user would be     able to read and write huge pages after they are freed and reallocated to a different process. This could     lead to privilege escalation, denial of service or information leaks. CVE-2021-4083 Jann Horn reported a     race condition in the local (Unix) sockets garbage collector, that can lead to use-after-free. A local     user could exploit this to cause a denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-4135 A flaw was found in the netdevsim driver which would lead to an     information leak. This driver is not enabled in Debian's official kernel configurations. CVE-2021-4155     Kirill Tkhai discovered a data leak in the way the XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for     a size increase of files with unaligned size. A local attacker can take advantage of this flaw to leak     data on the XFS filesystem. CVE-2021-4203 Jann Horn reported a race condition in the local (Unix) sockets     implementation that can lead to a use-after-free. A local user could exploit this to leak sensitive     information from the kernel. CVE-2021-20317 It was discovered that the timer queue structure could become     corrupt, leading to waiting tasks never being woken up. A local user with certain privileges could exploit     this to cause a denial of service (system hang). CVE-2021-20321 A race condition was discovered in the     overlayfs filesystem driver. A local user with access to an overlayfs mount and to its underlying upper     directory could exploit this for privilege escalation. CVE-2021-20322 An information leak was discovered     in the IPv4 implementation. A remote attacker could exploit this to quickly discover which UDP ports a     system is using, making it easier for them to carry out a DNS poisoning attack against that system.
    CVE-2021-22600 The syzbot tool found a flaw in the packet socket (AF_PACKET) implementation which could     lead to incorrectly freeing memory. A local user with CAP_NET_RAW capability (in any user namespace) could     exploit this for denial of service (memory corruption or crash) or possibly for privilege escalation.
    CVE-2021-28711, CVE-2021-28712, CVE-2021-28713 (XSA-391) Juergen Gross reported that malicious PV backends     can cause a denial of service to guests being serviced by those backends via high frequency events, even     if those backends are running in a less privileged environment. CVE-2021-28714, CVE-2021-28715 (XSA-392)     Juergen Gross discovered that Xen guests can force the Linux netback driver to hog large amounts of kernel     memory, resulting in denial of service. CVE-2021-38300 Piotr Krysiuk discovered a flaw in the classic BPF     (cBPF) JIT compiler for MIPS architectures. A local user could exploit this to excute arbitrary code in     the kernel. This issue is mitigated by setting sysctl net.core.bpf_jit_enable=0, which is the default. It     is *not* mitigated by disabling unprivileged use of eBPF. CVE-2021-39685 Szymon Heidrich discovered a     buffer overflow vulnerability in the USB gadget subsystem, resulting in information disclosure, denial of     service or privilege escalation. CVE-2021-39686 A race condition was discovered in the Android binder     driver, that could lead to incorrect security checks. On systems where the binder driver is loaded, a     local user could exploit this for privilege escalation. CVE-2021-39698 Linus Torvalds reported a flaw in     the file polling implementation, which could lead to a use-after-free. A local user could exploit this for     denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2021-39713 The     syzbot tool found a race condition in the network scheduling subsystem which could lead to a use-after-     free. A local user could exploit this for denial of service (memory corruption or crash) or possibly for     privilege escalation. CVE-2021-41864 An integer overflow was discovered in the Extended BPF (eBPF)     subsystem. A local user could exploit this for denial of service (memory corruption or crash), or possibly     for privilege escalation. This can be mitigated by setting sysctl kernel.unprivileged_bpf_disabled=1,     which disables eBPF use by unprivileged users. CVE-2021-42739 A heap buffer overflow was discovered in the     firedtv driver for FireWire-connected DVB receivers. A local user with access to a firedtv device could     exploit this for denial of service (memory corruption or crash), or possibly for privilege escalation.
    CVE-2021-43389 The Active Defense Lab of Venustech discovered a flaw in the CMTP subsystem as used by     Bluetooth, which could lead to an out-of-bounds read and object type confusion. A local user with     CAP_NET_ADMIN capability in the initial user namespace could exploit this for denial of service (memory     corruption or crash), or possibly for privilege escalation. CVE-2021-43975 Brendan Dolan-Gavitt reported a     flaw in the hw_atl_utils_fw_rpc_wait() function in the aQuantia AQtion ethernet device driver which can     result in denial of service or the execution of arbitrary code. CVE-2021-43976 Zekun Shen and Brendan     Dolan-Gavitt discovered a flaw in the mwifiex_usb_recv() function of the Marvell WiFi-Ex USB Driver. An     attacker able to connect a crafted USB device can take advantage of this flaw to cause a denial of     service. CVE-2021-44733 A race condition was discovered in the Trusted Execution Environment (TEE)     subsystem for Arm processors, which could lead to a use-after-free. A local user permitted to access a TEE     device could exploit this for denial of service (memory corruption or crash) or possibly for privilege     escalation. CVE-2021-45095 It was discovered that the Phone Network protocol (PhoNet) driver has a     reference count leak in the pep_sock_accept() function. CVE-2021-45469 Wenqing Liu reported an out-of-     bounds memory access in the f2fs implementation if an inode has an invalid last xattr entry. An attacker     able to mount a specially crafted image can take advantage of this flaw for denial of service.
    CVE-2021-45480 A memory leak flaw was discovered in the __rds_conn_create() function in the RDS (Reliable     Datagram Sockets) protocol subsystem. CVE-2022-0001 (INTEL-SA-00598) Researchers at VUSec discovered that     the Branch History Buffer in Intel processors can be exploited to create information side channels with     speculative execution. This issue is similar to Spectre variant 2, but requires additional mitigations on     some processors. This can be exploited to obtain sensitive information from a different security context,     such as from user-space to the kernel, or from a KVM guest to the kernel. CVE-2022-0002 (INTEL-SA-00598)     This is a similar issue to CVE-2022-0001, but covers exploitation within a security context, such as from     JIT-compiled code in a sandbox to hosting code in the same process. This can be partly mitigated by     disabling eBPF for unprivileged users with the sysctl: kernel.unprivileged_bpf_disabled=2. This update     does that by default. CVE-2022-0322 Eiichi Tsukata discovered a flaw in the sctp_make_strreset_req()     function in the SCTP network protocol implementation which can result in denial of service. CVE-2022-0330     Sushma Venkatesh Reddy discovered a missing GPU TLB flush in the i915 driver, resulting in denial of     service or privilege escalation. CVE-2022-0435 Samuel Page and Eric Dumazet reported a stack overflow in     the networking module for the Transparent Inter-Process Communication (TIPC) protocol, resulting in denial     of service or potentially the execution of arbitrary code. CVE-2022-0487 A use-after-free was discovered     in the MOXART SD/MMC Host Controller support driver. This flaw does not impact the Debian binary packages     as CONFIG_MMC_MOXART is not set. CVE-2022-0492 Yiqi Sun and Kevin Wang reported that the cgroup-v1     subsystem does not properly restrict access to the release-agent feature. A local user can take advantage     of this flaw for privilege escalation and bypass of namespace isolation. CVE-2022-0617 butt3rflyh4ck     discovered a NULL pointer dereference in the UDF filesystem. A local user that can mount a specially     crafted UDF image can use this flaw to crash the system. CVE-2022-0644 Hao Sun reported a missing check     for file read permission in the finit_module() and kexec_file_load() system calls. The security impact of     this is unclear, since these system calls are usually only available to the root user. CVE-2022-22942 It     was discovered that wrong file file descriptor handling in the VMware Virtual GPU driver (vmwgfx) could     result in information leak or privilege escalation. CVE-2022-24448 Lyu Tao reported a flaw in the NFS     implementation in the Linux kernel when handling requests to open a directory on a regular file, which     could result in a information leak. CVE-2022-24959 A memory leak was discovered in the     yam_siocdevprivate() function of the YAM driver for AX.25, which could result in denial of service.
    CVE-2022-25258 Szymon Heidrich reported the USB Gadget subsystem lacks certain validation of interface OS     descriptor requests, resulting in memory corruption. CVE-2022-25375 Szymon Heidrich reported that the     RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command, resulting in information leak     from kernel memory. For the oldstable distribution (buster), these problems have been fixed in version     4.19.232-1. This update additionally includes many more bug fixes from stable updates 4.19.209-4.19.232     inclusive. We recommend that you upgrade your linux packages.

The version of kernel installed on the remote host is prior to 5.4.156-83.273. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2025-099 advisory.

    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

    A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to     cause a denial of service. This vulnerability is similar with the older CVE-2019-18808. The highest threat     from this vulnerability is to system availability. (CVE-2021-3744)

    A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker     to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat     from this vulnerability is to system availability. (CVE-2021-3764)

    An out-of-bounds (OOB) memory write flaw was found in prealloc_elems_and_freelist in kernel/bpf/stackmap.c     in the bpf in the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an     integer overflow which could allow a local attacker, with a special user privilege, to gain access to out-     of-bounds memory leading to a system crash or a leak of internal kernel information.
