Security update for the Linux Kernel

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 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-2023-4385: 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).
