The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2022-4129: Fixed a denial of service with the Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. (bsc#1205711)
  • CVE-2021-4203: Fixed use-after-free read flaw that was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (bsc#1194535).
  • CVE-2023-23559: Fixed integer overflow in rndis_wlan that leads to a buffer overflow (bsc#1207051).
  • CVE-2023-26545: Fixed double free in net/mpls/af_mpls.c upon an allocation failure (bsc#1208700).
  • CVE-2022-38096: Fixed NULL-ptr deref in vmw_cmd_dx_define_query() (bsc#1203331).
  • CVE-2022-36280: Fixed out-of-bounds memory access vulnerability found in vmwgfx driver (bsc#1203332).
  • CVE-2023-0045: Fixed missing Flush IBP in ib_prctl_set (bsc#1207773).
  • CVE-2023-0590: Fixed race condition in qdisc_graft() (bsc#1207795).
  • CVE-2022-2991: Fixed an heap-based overflow in the lightnvm implemenation (bsc#1201420).

The following non-security bugs were fixed:

  • kabi/severities: add l2tp local symbols
