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-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race
    condition in bt_sock_recvmsg (bsc#1218610).
