The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security bugfixes.

The following security bugs were fixed:

- CVE-2023-4921: Fixed a use-after-free vulnerability in the QFQ network scheduler which could be exploited to achieve local privilege escalatio (bsc#1215275).
- CVE-2023-4622: Fixed a use-after-free vulnerability in the af_unix component which could be exploited to achieve local privilege escalation. (bsc#1215117)
- CVE-2023-4623: Fixed a use-after-free issue in the HFSC network scheduler which could be exploited to achieve local privilege escalation (bsc#1215115).
- CVE-2023-4881: Fixed a out-of-bounds write flaw in the netfilter subsystem that could lead to potential information disclosure or a denial of service (bsc#1215221).
- CVE-2023-40283: Fixed a use-after-free issue in the Bluetooth subsystem (bsc#1214233).
- CVE-2023-1192: Fixed a use-after-free in the CIFS subsystem (bsc#1208995).
- CVE-2022-36402: Fixed an integer overflow vulnerability in vmwgfx driver in that allowed a local attacker with a user account on the system to gain privilege (bsc#1203517).
- CVE-2023-20588: Fixed a potential data leak that could be triggered through a side channel when division by zero occurred on some AMD processors (bsc#1213927).
- CVE-2023-4134: Fixed use-after-free in cyttsp4_watchdog_work() (bsc#1213971).
- CVE-2023-3863: Fixed a use-after-free flaw was found in nfc_llcp_find_local that allowed a local user with special privileges to impact a kernel information leak issue (bsc#1213601).
- CVE-2023-4459: Fixed a NULL pointer dereference flaw in vmxnet3_rq_cleanup that may have allowed a local attacker with normal user privilege to cause a denial of service (bsc#1214451).
- CVE-2023-3772: Fixed a flaw in XFRM subsystem that may have allowed a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer leading to a possible kernel crash and denial of service (bsc#1213666).
- CVE-2023-2007: Fixed a flaw in the DPT I2O Controller driver that could allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel (bsc#1210448).
- CVE-2023-4385: Fixed a NULL pointer dereference flaw in dbFree that may have allowed a local attacker to crash the system due to a missing sanity check (bsc#1214348).
- CVE-2023-4387: Fixed use-after-free flaw in vmxnet3_rq_alloc_rx_buf that could allow a local attacker to crash the system due to a double-free (bsc#1214350).
- CVE-2023-4128: Fixed a use-after-free flaw in net/sched/cls_fw.c that allowed a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue (bsc#1214149).
- CVE-2023-34319: Fixed buffer overrun triggered by unusual packet in xen/netback (XSA-432) (bsc#1213546).

The following non-security bugs were fixed:

- x86/retpoline: Do not clobber RFLAGS during srso_safe_ret() (git-fixes).
- x86/speculation: Mark all Skylake CPUs as vulnerable to GDS (git-fixes).
- x86/srso: Correct the mitigation status when SMT is disabled (git-fixes).
- x86/srso: Disable the mitigation on unaffected configurations (git-fixes).
- x86/tlb: Flush global mappings when KAISER is disabled (bsc#1190194, bsc#1213902).
