  <description>
The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- 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-2023-3772: 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-2023-3863: 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-2023-4128: 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-2023-4132: Fixed use-after-free vulnerability was found in the siano smsusb module that allowed a local user to crash the system, causing a denial of service condition (bsc#1213969).
- CVE-2023-4134: Fixed use-after-free in cyttsp4_watchdog_work() (bsc#1213971).
- CVE-2023-4273: Fixed a flaw in the exFAT driver of the Linux kernel that alloawed a local privileged attacker to overflow the kernel stack (bsc#1214120).
- 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-2023-4459: 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-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, causing a denial of service (bsc#1203517).
- CVE-2023-20588: Fixed a division-by-zero error on some AMD processors that can potentially return speculative data resulting in loss of confidentiality (bsc#1213927).
- CVE-2023-21400: Fixed several memory corruptions due to improper locking in io_uring (bsc#1213272).

The following non-security bugs were fixed:

- kabi/severities: Ignore newly added SRSO mitigation functions
- x86/cpu/kvm: Provide UNTRAIN_RET_VM (git-fixes).
- x86/cpu: Cleanup the untrain mess (git-fixes).
- x86/cpu: Rename original retbleed methods (git-fixes).
- x86/cpu: Rename srso_(.*)_alias to srso_alias_\1 (git-fixes).
- x86/retpoline: Do not clobber RFLAGS during srso_safe_ret() (git-fixes).
- x86/speculation: Add cpu_show_gds() prototype (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/srso: Explain the untraining sequences a bit more (git-fixes).
- x86: Move gds_ucode_mitigated() declaration to header (git-fixes).
