Security update for the Linux Kernel

This security update for the SUSE Linux Enterprise 15 SP6 RT kernel addresses a broad set of security vulnerabilities identified by numerous CVEs (e.g., CVE-2024-26924, CVE-2024-27397, CVE-2024-50262, CVE-2024-53113). The fixes cover issues such as improper locking in SCSI lpfc driver, timeout handling in netfilter nf_tables, out-of-bounds writes in BPF, memory leaks in vsock, null pointer dereferences in nilfs2 and zram, use-after-free in SMB client and btrfs, and race conditions in MPTCP and RCU subsystems. These vulnerabilities could lead to system instability, crashes, or memory corruption if exploited. The update also includes fixes for various non-security bugs improving kernel functionality and hardware compatibility.

The vulnerabilities fixed in this update could allow local or remote attackers to cause system crashes, memory corruption, or denial of service due to race conditions, use-after-free, null pointer dereferences, and improper resource handling. The impact varies by vulnerability but generally affects kernel stability and security. No known exploits in the wild have been reported for these issues at the time of this advisory.

A security update for the SUSE Linux Enterprise 15 SP6 RT kernel has been released that addresses these vulnerabilities. Users should apply this official update to mitigate the risks. Patch status is confirmed by the vendor advisory indicating an official fix. No additional mitigation steps are specified beyond applying the update.
