The SUSE Linux Enterprise 15 SP5 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2023-39194: Fixed a flaw in the processing of state filters which could allow a local attackers to disclose sensitive information. (bsc#1215861) - CVE-2023-39193: Fixed a flaw in the processing of state filters which could allow a local attackers to disclose sensitive information. (bsc#1215860) - CVE-2023-39192: Fixed a flaw in the u32_match_it function which could allow a local attackers to disclose sensitive information. (bsc#1215858) - CVE-2023-42754: Fixed a null pointer dereference in ipv4_link_failure which could lead an authenticated attacker to trigger a DoS. (bsc#1215467) - 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-2023-4155: 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. (bsc#1214022) - 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-2023-42753: 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-2023-1859: Fixed a use-after-free flaw in Xen transport for 9pfs which could be exploited to crash the system (bsc#1210169). - CVE-2023-4881: Fixed a out-of-bounds write flaw in the netfilter subsystem that could lead to potential information disclosure or a denial of service (bsc#1215221). - CVE-2023-2177: Fixed a null pointer dereference issue in the sctp network protocol which could allow a user to crash the system (bsc#1210643). - CVE-2023-1192: Fixed use-after-free in cifs_demultiplex_thread() (bsc#1208995).
