Title of the patch: Security update for the Linux Kernel
Description of the patch:
The SUSE Linux Enterprise 12 SP5 RT kernel was updated to receive various security and bugfixes.
- 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-2022-38096: Fixed NULL-ptr deref in vmw_cmd_dx_define_query() (bsc#1203331).
- 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-2023-0597: Fixed lack of randomization of per-cpu entry area in x86/mm (bsc#1207845).

- 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).
The following non-security bugs were fixed:
