AI-suggested
A patch is available and should be applied promptly. Users must update their systems to the fixed package versions (5.4.0-1124.134, 5.4.0-1150.160+fips1, 5.4.0-1153.162+fips1) via standard system updates. After updating, a system reboot is required to apply the changes. Due to an ABI change, all third-party kernel modules must be recompiled and reinstalled. If standard kernel metapackages are installed, the upgrade process will handle this automatically. Follow the Ubuntu advisory USN-7754-2 for detailed instructions.
Description
Multiple security vulnerabilities were identified in the Linux kernel's network traffic control subsystem affecting FIPS-certified kernel packages for AWS, GCP, and generic Linux. These flaws could potentially allow an attacker to compromise the system. The issues are addressed by updates that require a system reboot and recompilation of third-party kernel modules due to ABI changes. Fixed versions have been released and are available through Ubuntu Pro updates.
