Multiple security vulnerabilities were discovered in the Linux kernel affecting the network traffic control subsystem. These flaws could potentially allow an attacker to compromise affected systems. The issues impact Linux kernel versions used in Ubuntu 22.04 LTS and 24.04 LTS releases, specifically the linux-gcp-6.8 and linux-raspi kernels. Fixes have been released and are available via standard system updates, which require a reboot and recompilation of third-party kernel modules due to ABI changes.
