CVE-2026-23264

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

Published Mar 18, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
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)
