Multiple security vulnerabilities were discovered in the Linux kernel affecting numerous subsystems including architectures (ARM64, S390, x86), various drivers, file systems, networking protocols, and virtualization components. These flaws could potentially allow an attacker to compromise the system. Fixes have been released for affected Linux kernel versions used in Ubuntu 24.04 LTS and 26.04 LTS, including linux-gcp and linux-oem kernels. Users are advised to update to the patched kernel versions and reboot to apply the fixes. Due to ABI changes, recompilation of third-party kernel modules is required after updating.
