  - In QEMU 4.2.0, a MemoryRegionOps object may lack read/write callback methods, leading to a NULL pointer     dereference. (CVE-2020-15469)

  - A flaw was found in the memory management API of QEMU during the initialization of a memory region cache.
    This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO     operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial     of service. This flaw affects QEMU versions prior to 5.2.0. (CVE-2020-27821)

  - An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of     QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an     interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said     issue while updating controller state fields and their subsequent processing. A privileged guest user may     use this flaw to crash the QEMU process on the host resulting in DoS scenario. (CVE-2021-20221)

  - The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to     the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This     flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of     service or potential code execution. QEMU up to (including) 5.2.0 is affected by this. (CVE-2021-3409)

  - A divide-by-zero issue was found in dwc2_handle_packet in hw/usb/hcd-dwc2.c in the hcd-dwc2 USB host     controller emulation of QEMU. A malicious guest could use this flaw to crash the QEMU process on the host,     resulting in a denial of service. (CVE-2020-27661)

  - A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI     I/O requests in the case of an error mptsas_free_request() that does not dequeue the request object 'req'     from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the     host, resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected.
    (CVE-2021-3392)

  - A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a     single, large transfer request, to reduce the overhead and improve performance. The combined size of the     bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper     validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the     array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a     denial of service. (CVE-2021-3527)

  - Several memory leaks were found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions     up to and including 6.0. They exist in contrib/vhost-user-gpu/vhost-user-gpu.c and contrib/vhost-user-     gpu/virgl.c due to improper release of memory (i.e., free) after effective lifetime. (CVE-2021-3544)

  - An information disclosure vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of     QEMU in versions up to and including 6.0. The flaw exists in virgl_cmd_get_capset_info() in contrib/vhost-     user-gpu/virgl.c and could occur due to the read of uninitialized memory. A malicious guest could exploit     this issue to leak memory from the host. (CVE-2021-3545)

  - An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of     QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET'     command from the guest. It could allow a privileged guest user to crash the QEMU process on the host,     resulting in a denial of service condition, or potential code execution with the privileges of the QEMU     process.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-9565 advisory.

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to     5.14-rc7. (CVE-2021-3653)

  - kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE) (CVE-2021-3656)

  - The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It     may use the notification thread attributes object (passed through its struct sigevent parameter) after it     has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified     other impact. (CVE-2021-33574)

  - The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when     processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in     degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
    (CVE-2021-27645)

  - The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in     parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in     a denial of service or disclosure of information. This occurs because atoi was used but strtoul should     have been used to ensure correct calculations. (CVE-2021-35942)

  - Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument     in some cases where the input length is close to the maximum permissable length for an integer on the     platform. In such cases the return value from the function call will be 1 (indicating success), but the     output length value will be negative. This could cause applications to behave incorrectly or crash.
    OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to     OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out     of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should     upgrade to 1.0.2y. Other users should upgrade to 1.1.1j.

    Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x). (CVE-2021-23840)

  - The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based     on the issuer and serial number data contained within an X509 certificate. However it fails to correctly     handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is     maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a     potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by     OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on     certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are     affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x     and below are affected by this issue.

  - nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-     free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a     certain point during device setup, aka CID-b98e762e3d71. (CVE-2021-3348)

  - In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free. This could     lead to local information disclosure with no additional execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-140550171     (CVE-2020-0427)

  - A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.
    drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID,     aka CID-c8bcd9c5be24. (CVE-2020-29660)

  - mwifiex_cmd_802_11_ad_hoc_start in drivers/net/wireless/marvell/mwifiex/join.c in the Linux kernel through     5.10.4 might allow remote attackers to execute arbitrary code via a long SSID value, aka CID-5c455c5ab332.
    (CVE-2020-36158)

  - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-     device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege 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 system     availability. (CVE-2021-31916)

  - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel     privilege escalation from the context of a network service or an unprivileged process. If     sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the     auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network     service privileges to escalate to root or from the context of an unprivileged user directly if a     BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)

  - A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked     down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to further increase their privileges to that of a     running kernel. (CVE-2020-27777)

  - A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way     user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev()     together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(),     hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their     privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and     WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to     inject arbitrary data frames independent of the network configuration. (CVE-2020-26140)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was     found in the way user uses trace ring buffer in a specific way. Only privileged local users (with     CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - 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)

  - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and     WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can     abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042     (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26144)

  - 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 on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations     reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate     selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the     WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by     design. (CVE-2020-26146)

  - An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-     bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)

  - 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)

  - kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading     to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not     protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized     data that might represent sensitive information previously operated on by the kernel. (CVE-2021-31829)

  - 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)

  - 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)

  - 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)

  - 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)

  - A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the     system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access. (CVE-2021-0129)

  - kernel: overlayfs: Mounting overlayfs inside an unprivileged user namespace can reveal files     (CVE-2021-3732)

  - Improper input validation in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4     and before version 1.4.29.0 for Windows*, may allow an authenticated user to potentially enable a denial     of service via local access. (CVE-2020-24502)

  - 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)

  - Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers for Linux before version 1.0.4     may allow an authenticated user to potentially enable information disclosure via local access.
    (CVE-2020-24503)

  - Uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers for Linux before version     1.0.4 may allow an authenticated user to potentially enable denial of service via local access.
    (CVE-2020-24504)

  - An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The     copy-on-write implementation can grant unintended write access because of a race condition in a THP     mapcount check, aka CID-c444eb564fb1. (CVE-2020-29368)

  - There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config     params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y ,     CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution,     the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap     overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly     privileges escalation. (CVE-2021-20194)

  - kernel: eBPF 32-bit source register truncation on div/mod (CVE-2021-3600)

  - A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with     root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands.
    (CVE-2021-3635)

  - kernel: NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (CVE-2021-3659)

  - An issue was discovered in the Linux kernel before 5.11.11. tipc_nl_retrieve_key in net/tipc/node.c does     not properly validate certain data sizes, aka CID-0217ed2848e8. (CVE-2021-29646)
