## Description:

The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed:

* 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-2023-2007: 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-2023-20588: Fixed a division-by-zero error on some AMD processors that
can potentially return speculative data resulting in loss of confidentiality
(bsc#1213927).
* CVE-2023-3772: 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-2023-3812: Fixed an out-of-bounds memory access flaw in the TUN/TAP
device driver functionality that could allow a local user to crash or
potentially escalate their privileges on the system (bsc#1213543).
* 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-2023-4385: 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).

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: Fix __x86_return_thunk symbol type (git-fixes).
* x86/cpu: Fix up srso_safe_ret() and __x86_return_thunk() (git-fixes).
* x86/cpu: Rename original retbleed methods (git-fixes).
* x86/cpu: Rename srso_(.*) _alias to srso_alias_ \1 (git-fixes).
* x86/retpoline,kprobes: Fix position of thunk sections with CONFIG_LTO_CLANG
(git-fixes).
* x86/retpoline,kprobes: Skip optprobe check for indirect jumps with
retpolines and IBT (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/srso: Fix build breakage with the LLVM linker (git-fixes).
* x86: Move gds_ucode_mitigated() declaration to header (git-fixes).
