CVE-2026-90289 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Resize MST HDCP per-connector arrays to 32
AMDGPU_DM_MAX_DISPLAY_INDEX is 31. It suggest a maximum number of 32 connectors. But the way it's used is like MAX_DISPLAY_COUNT. Hence we're off by one with DRM core, which supports a max of 32 connectors.
Rename AMDGPU_DM_MAX_DISPLAY_INDEX to AMDGPU_DM_MAX_DISPLAY_COUNT to match its actual use, and increase the size to 32 to match the originally intended size.
