AI-suggested
A patch is available and should be applied promptly. Users should update their Linux kernel packages to the fixed versions listed in the vendor advisory (e.g., 6.8.0-1031.33~22.04.1 and others). 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. Standard system upgrades will handle this automatically unless kernel metapackages have been manually removed.
Description
Multiple security vulnerabilities were discovered in the Linux kernel affecting subsystems including InfiniBand drivers, Netfilter, and network traffic control. These flaws could potentially allow an attacker to compromise the affected system. The issues impact various Linux kernel packages including linux-aws-6.8 and others. Fixes have been released and are available in updated kernel versions. Users are advised to apply these updates and reboot their systems. Due to ABI changes, recompilation of third-party kernel modules may be necessary.
