## The brief

Canonical has issued kernel fixes for Ubuntu 22.04 LTS systems using the FIPS variant. USN-8818-6 covers several subsystems, including an Arm memory-ordering flaw that could let a local attacker bypass revoked write permissions or gain privileges. The advisory lists linux-image-5.15.0-194-fips version 5.15.0-194.204+fips1 through Ubuntu Pro's FIPS Updates. Applying the update requires a reboot; its ABI change requires rebuilding installed third-party kernel modules.
