Multiple security vulnerabilities were discovered in the Linux kernel affecting the NTFS3 file system and network traffic control subsystems. These flaws could potentially allow an attacker to compromise the system. Fixes have been released for various Linux kernel versions used in Ubuntu 20.04 LTS and 22.04 LTS, including kernels for IBM cloud, Google Container Engine, and KVM environments. Users are advised to update and reboot their systems to apply the patches. Due to ABI changes, third-party kernel modules may need recompilation after the update.
