The SUSE Linux Enterprise 12 SP5 Azure 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-2023-3772: Fixed a flaw in XFRM subsystem that may have allowed a malicious user with CAPNETADMIN 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 nfcllcpfind_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-2023-4133: Fixed use after free bugs caused by circular dependency problem in cxgb4 (bsc#1213970).
CVE-2023-4134: Fixed use-after-free in cyttsp4watchdogwork() (bsc#1213971).
CVE-2023-4194: Fixed a type confusion in net tunchropen() (bsc#1214019).
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 vmxnet3rqallocrxbuf 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 vmxnet3rqcleanup that may have allowed a local attacker with normal user privilege to cause a denial of service (bsc#1214451).
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-2023-34319: Fixed buffer overrun triggered by unusual packet in xen/netback (XSA-432) (bsc#1213546).
CVE-2023-40283: Fixed use-after-free in l2capsockready_cb (bsc#1214233).
