Description OSIDB Bzimport 2025-04-01 16:02:05 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix null check for pipe_ctx->plane_state in resource_build_scaling_params

Null pointer dereference issue could occur when pipe_ctx->plane_state
is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not
null before accessing. This prevents a null pointer dereference.

Found by code review.

(cherry picked from commit 63e6a77ccf239337baa9b1e7787cde9fa0462092)
