AI-suggested
A patch is available and should be applied promptly by updating to the fixed kernel versions 5.15.0-1104.111+fips1, 5.15.0-174.184+fips1, or 5.15.0-1104.113+fips1 as appropriate. After updating, a system reboot is required to activate the fixes. Due to an ABI change in the kernel, all third-party kernel modules must be recompiled and reinstalled. Follow the vendor's update instructions carefully to ensure full remediation.
Description
Multiple security vulnerabilities were identified in the Linux kernel affecting ARM64 architecture, Cryptographic API, Netfilter, and network traffic control subsystems. These flaws could potentially allow an attacker to compromise the system. The issues affect various linux-fips kernel variants including linux-aws-fips and linux-gcp-fips. Fixes have been released in updated kernel versions, and a system reboot is required after applying the updates. Due to an ABI change, third-party kernel modules must be recompiled and reinstalled after the update.
