## Description:

This update for the Linux Kernel 5.14.21-150500_53 fixes several issues.

The following security issues were fixed:

  * CVE-2023-6531: Fixed a use-after-free flaw due to a race problem in the unix
    garbage collector's deletion of SKB races with unix_stream_read_generic()on
    the socket that the SKB is queued on (bsc#1218487).
  * CVE-2023-46813: Fixed a local privilege escalation with user-space programs
    that have access to MMIO regions (bsc#1216898).
  * CVE-2023-39191: Fixed a lack of validation of dynamic pointers within user-
    supplied eBPF programs that may have allowed an attacker with CAP_BPF
    privileges to escalate privileges and execute arbitrary code. (bsc#1215863)
  * CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race
    condition in bt_sock_recvmsg (bsc#1218610).
  * CVE-2023-0461: Fixed use-after-free in icsk_ulp_data (bsc#1208911).
