NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_7_67-rt package and not the kernel-livepatch-6_4_0-150700_7_67-rt package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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

drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()

When media GT is disabled via configfs, there is no allocation for media_gt, which is kept as NULL. In such scenario, intel_hdcp_gsc_check_status() results in a kernel pagefault error due to &gt->uc.gsc being evaluated as an invalid memory address.

Fix that by introducing a NULL check on media_gt and bailing out early if so.

While at it, also drop the NULL check for gsc, since it can't be NULL if media_gt is not NULL.

v2:

  • Get address for gsc only after checking that gt is not NULL. (Shuicheng)
  • Drop the NULL check for gsc. (Shuicheng) v3:
  • Add "Fixes" and "Cc: <stable...>" tags. (Matt)

(cherry picked from commit bfaf87e84ca3ca3f6e275f9ae56da47a8b55ffd1)
