Multiple security vulnerabilities were identified in the Linux kernel, specifically affecting the Overlay file system and Network traffic control subsystems. These flaws could potentially allow an attacker to compromise affected systems. The vulnerabilities impact the linux-raspi-realtime kernel versions prior to 6.8.0-2029.30 and 6.8.1-1031.32, as well as several specific 6.7.0 and 6.8.0 builds. A patch has been released and is available through Ubuntu security updates. Users must reboot after updating and recompile any third-party kernel modules due to an ABI change.
