A use-after-free vulnerability in the Linux kernel's vsock/vmci subsystem was fixed by Red Hat. The flaw occurred during a peer reset connection in the handshake phase, causing improper socket cleanup and leading to a use-after-free condition detected by KASAN. This vulnerability has a high severity score of 8.8 and affects multiple Linux kernel versions prior to specific 5.15.x updates. Official kernel updates have been released to address this issue. Users should apply these updates and reboot to mitigate the vulnerability.

A high severity vulnerability (CVE-2026-22984) in the Linux kernel's libceph component was resolved by adding explicit bounds checking to prevent potential out-of-bounds reads in the handle_auth_done() function. This vulnerability could lead to serious impacts including confidentiality, integrity, and availability violations. The issue affects multiple Linux kernel versions prior to specific patched releases. Ubuntu has released security updates addressing this and numerous other kernel vulnerabilities. Users are advised to update to the fixed kernel versions and reboot their systems. Due to ABI changes, recompilation of third-party kernel modules may be necessary.

This security update provides a functional equivalent of RHSA-2026:75576. The original Red Hat(R) advisory is available from the Red Hat web site at https://access.redhat.com/errata/RHSA-2026:75576.
