CVE-2024-43903 Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for \'afb\' before dereferencing in amdgpu_dm_plane_handle_cursor_update
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.
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)
