This update includes several security related package updates from AlmaLinux only. In particular it includes fixes for the two critical kernel bugs GhostLock CVE-2026-43499) and Januscape (CVE-2026-53359). Note that Qlustar 14/Ubuntu already received fixes for both of these with the release 14.1.5 from July 4th.

Important: The Qlustar 13 kernel 5.15.x is still vulnerable to both GhostLock and Januscape. It seems kernel developers are heavily overloaded and have decided to focus on the most recent LTS kernels for security fixes. In the light of this, we highly recommend to update Qlustar 13 systems to Qlustar 14 as soon as possible. Nevertheless, we will provide patched Qlustar 13 kernels as soon as they are available from upstream.
