  "title": "drm/amd/display: Add NULL check for clk_mgr and clk_mgr-\u003Efuncs in dcn401_init_hw",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Add NULL check for clk_mgr and clk_mgr-\u003Efuncs in dcn401_init_hw  This commit addresses a potential null pointer dereference issue in the \u0060dcn401_init_hw\u0060 function. The issue could occur when \u0060dc-\u003Eclk_mgr\u0060 or \u0060dc-\u003Eclk_mgr-\u003Efuncs\u0060 is null.  The fix adds a check to ensure \u0060dc-\u003Eclk_mgr\u0060 and \u0060dc-\u003Eclk_mgr-\u003Efuncs\u0060 is not null before accessing its functions. This prevents a potential null pointer dereference.  Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:416 dcn401_init_hw() error: we previously assumed \u0027dc-\u003Eclk_mgr\u0027 could be null (see line 225)",
