  - Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making     it go out-of-memory via icmp6 packets of type 130 or 131. We recommend upgrading past commit     2d3916f3189172d5c69d33065c3c21119fe539fc. (CVE-2022-0742)

  - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - An out-of-bounds (OOB) memory write flaw was found in the Linux kernel's watch_queue event notification     subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain     privileged access or cause a denial of service on the system. (CVE-2022-0995)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
    This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers     concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM     for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the     system. (CVE-2022-1048)

  - 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)

  - 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 PV device frontends vulnerable to attacks by backends T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV     device frontends are using the grant table interfaces for removing access rights of the backends in ways     being subject to race conditions, resulting in potential data leaks, data corruption by malicious     backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the     gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they     assume that a following removal of the granted access will always succeed, which is not true in case the     backend has mapped the granted page between those two operations. As a result the backend can keep access     to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.
    The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of     a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038     gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,     9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no     longer in use, but the freeing of the related data page is not synchronized with dropping the granted     access. As a result the backend can keep access to the memory page even after it has been freed and then     re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to     revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which     can be triggered by the backend. CVE-2022-23042 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038,     CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)

  - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of     the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)

  - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,     aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to     influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive     information. (CVE-2022-23960)

  - drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.
    (CVE-2022-24958)

  - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has     EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

  - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and     net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap     objects and may cause a local privilege escalation threat. (CVE-2022-27666)

  - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)

  - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28388)

  - mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28389)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring     timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race     condition perhaps can only be exploited infrequently. (CVE-2022-29582)
