AI-suggested
A security update fixing these vulnerabilities is available in linux-aws-fips version 6.8.0-1065.68+fips1. Users should apply this update promptly and reboot their systems to ensure all changes take effect. Due to an ABI change, recompilation and reinstallation of third-party kernel modules may be required. Follow the official Ubuntu security notice USN-8817-2 for detailed update instructions.
Description
Multiple security vulnerabilities were discovered in the Linux kernel for AWS FIPS systems, including a critical issue affecting some Arm processors. This issue allows a local attacker to write to memory after permission has been revoked by exploiting a race condition in translation lookaside buffer (TLB) invalidation. Additional flaws affect various kernel subsystems such as network drivers, InfiniBand, and IPv4/IPv6 networking. These vulnerabilities could allow attackers to bypass memory protections or escalate privileges. A security update is available that addresses these issues.
