AI-suggested
A patch is available and should be applied immediately by updating to linux-aws-6.8 kernel versions 6.8.0-1065.68 or 6.8.0-1065.68~22.04.1 as appropriate for your Ubuntu release. After updating, a system reboot is required to activate the fixes. Due to an unavoidable ABI change, all third-party kernel modules must be recompiled and reinstalled. Standard system upgrades will handle this automatically unless kernel metapackages have been manually removed.
Description
Multiple security vulnerabilities were discovered in the Linux kernel for AWS systems, including a critical issue affecting some ARM processors. This ARM64 flaw allows a local attacker to write to memory after permissions were revoked by exploiting a timing issue with the translation lookaside buffer (TLB) invalidation. Additional vulnerabilities affect various kernel subsystems such as InfiniBand, network drivers, and multiple networking protocols. These issues could potentially allow attackers to bypass memory protections or escalate privileges. Fixes have been released and are available in updated linux-aws-6.8 kernel packages. A system reboot is required after applying updates, and third-party kernel modules may need recompilation due to ABI changes.
