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

drm/amd/display: Fix dsc eDP issue

[why]
Need to add function hook check before use
Published: 2026-05-08
Score: 5.5 Medium
EPSS: < 1% Very Low
KEV: No

AI Analysis

Impact

The AMD display driver in the Linux kernel lacks a verification step before invoking a function pointer associated with DSC eDP. The description indicates that this oversight could result in a null‑pointer dereference when the callback is uninitialized. The potential consequence is inferred to be a kernel crash, which would lead to a denial‑of‑service scenario.

Affected Systems

Any Linux kernel that includes the unpatched AMD display driver code is potentially affected. All distributions shipping such kernels or custom builds that incorporate the driver prior to the cited commits could be impacted. No specific version ranges are provided in the data.

Risk and Exploitability

The EPSS score is < 1% and the vulnerability is not listed in CISA’s KEV catalog, indicating no known public exploits. The CVSS score of 5.5 indicates a medium severity. Based on the description, the attack vector likely requires local or privileged execution, as the driver is triggered by display interface operations. An attacker with such access could exercise the faulty routine and induce the crash, but remote exploitation appears unlikely without additional vulnerabilities.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest kernel update that includes the AMD display driver patch (commit 0481be9f12d8324789ccebf1e5fd0704b6e3fc99 or later).
  • If kernel upgrade is not possible, rebuild the AMD display module with the patched code or disable AMD display functionality until the patch is deployed.
  • Reboot the system after applying the patch or modifying the driver to ensure the updated module is loaded.
