Technical description

In the Linux kernel, the following vulnerability has been resolved:

Revert "drm/amd: Check if ASPM is enabled from PCIe subsystem"

This reverts commit 7294863a6f01248d72b61d38478978d638641bee.

This commit was erroneously applied again after commit 0ab5d711ec74

("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device")

removed it, leading to very hard to debug crashes, when used with a system with two

AMD GPUs of which only one supports ASPM.

(cherry picked from commit 97a9689300eb2b393ba5efc17c8e5db835917080)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
