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-2023-39191: 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).
