The SUSE Linux Enterprise 15 SP5 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2023-39194: Fixed an out of bounds read in the XFRM subsystem (bsc#1215861). - CVE-2023-39193: Fixed an out of bounds read in the xtables subsystem (bsc#1215860). - CVE-2023-39192: Fixed an out of bounds read in the netfilter (bsc#1215858). - CVE-2023-42754: Fixed a NULL pointer dereference in the IPv4 stack that could lead to denial of service (bsc#1215467). - CVE-2023-4389: Fixed a reference counting issue in the Btrfs filesystem that could be exploited in order to leak internal kernel information or crash the system (bsc#1214351). - CVE-2023-5345: fixed an use-after-free vulnerability in the fs/smb/client component which could be exploited to achieve local privilege escalation. (bsc#1215899) - CVE-2023-42753: Fixed an array indexing vulnerability in the netfilter subsystem. This issue may have allowed a local user to crash the system or potentially escalate their privileges (bsc#1215150). - CVE-2023-1206: Fixed a hash collision flaw in the IPv6 connection lookup table. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95% (bsc#1212703). - 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 Unix domain sockets 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-2023-4155: Fixed a flaw in KVM AMD Secure Encrypted Virtualization (SEV). An attacker can trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel configurations without stack guard pages.
