In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing
This commit adds null checks for the 'stream' and 'plane' variables in the dcn30applyidlepoweroptimizations function. These variables were previously assumed to be null at line 922, but they were used later in the code without checking if they were null. This could potentially lead to a null pointer dereference, which would cause a crash.
The null checks ensure that 'stream' and 'plane' are not null before they are used, preventing potential crashes.
Fixes the below static smatch checker: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30hwseq.c:938 dcn30applyidlepoweroptimizations() error: we previously assumed 'stream' could be null (see line 922) drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30hwseq.c:940 dcn30applyidlepoweroptimizations() error: we previously assumed 'plane' could be null (see line 922)
