In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for clkmgr in dcn32init_hw
This commit addresses a potential null pointer dereference issue in the
dcn32_init_hwfunction. The issue could occur whendc->clk_mgris null.The fix adds a check to ensure
dc->clk_mgris not null before accessing its functions. This prevents a potential null pointer dereference.Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn32/dcn32hwseq.c:961 dcn32inithw() error: we previously assumed 'dc->clkmgr' could be null (see line 782)
