Multiple security vulnerabilities were discovered in the Linux kernel affecting the Cryptographic API and SMB network file system subsystems. These flaws could potentially allow an attacker to compromise the affected system. The vulnerabilities impact various FIPS-certified Linux kernel packages used in AWS, Azure, GCP, and standard Linux environments. Fixes have been released and are available through Ubuntu Pro updates. A system reboot and recompilation of third-party kernel modules are required after applying the updates.
