In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for afb in amdgpu_dm_plane_handle_cursor_update (v2) This commit adds a null check for the afb variable in the amdgpu_dm_plane_handle_cursor_update function. Previously, afb was assumed to be null, but was used later in the code without a null check. This could potentially lead to a null pointer dereference. Changes since v1: - Moved the null check for afb to the line where afb is used. (Alex) Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1298 amdgpu_dm_plane_handle_cursor_update() error: we previously assumed afb could be null (see line 1252)
