Security update for the Linux Kernel

This security update for the SUSE Linux kernel addresses a broad set of vulnerabilities identified by multiple CVEs, including CVE-2024-53164, CVE-2024-57891, CVE-2024-57951, CVE-2024-57952, CVE-2024-58090, CVE-2025-22034, CVE-2025-22077, CVE-2025-23141, and many others. The fixes cover kernel components such as network scheduling, high-resolution timers, memory management, KVM virtualization, btrfs filesystem, SCSI, USB HID, io_uring, and more. The update mitigates issues like improper interrupt handling, race conditions, use-after-free, null pointer dereferences, and deadlocks that could potentially affect system reliability and security. The vendor has released this update to patch these vulnerabilities in the affected SUSE Linux kernel versions.

The vulnerabilities fixed in this update could lead to system instability, kernel crashes, denial of service, or potential privilege escalation if exploited. The wide range of affected kernel components indicates that multiple attack vectors were addressed. However, no known exploits in the wild have been reported at this time. The update improves the security posture of SUSE Linux Enterprise Server 16.0 and SUSE Linux Micro 6.2 by resolving these kernel-level issues.

A security update has been released by SUSE to address these vulnerabilities. Users of SUSE Linux Enterprise Server 16.0 and SUSE Linux Micro 6.2 should apply the official kernel update provided by SUSE as soon as possible to mitigate these security issues. Patch status is confirmed by the vendor advisory indicating that fixes are available. No additional mitigation steps are specified beyond applying the update.
