AI-suggested
A patch is available and should be applied by updating the Linux kernel to version 7.0.0 or later as provided by the vendor. After updating, a system reboot is required to complete the remediation. Due to an ABI change, third-party kernel modules must be recompiled and reinstalled. Follow the vendor's update instructions carefully. No additional mitigation actions are indicated by the vendor advisory.
Description
A NULL pointer dereference vulnerability in the Linux kernel's drm/amd/ras component was fixed, addressing a flaw where ras_core could be NULL and accessed improperly. This issue was resolved in Linux kernel versions 7.0.0 and later. The vulnerability has a medium severity score and does not impact confidentiality or integrity but can cause denial of service via system crash. Multiple Linux kernel security issues were addressed in the same update, including fixes for AMD Zen 2 processor resource isolation. The vendor has released patches for affected versions and recommends updating and rebooting to apply fixes.
