Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Add NULL check for clk_mgr in dcn32_init_hw

This commit addresses a potential null pointer dereference issue in the dcn32_init_hw function. The issue could occur when dc->clk_mgr is null.

The fix adds a check to ensure dc->clk_mgr 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/dcn32/dcn32_hwseq.c:961 dcn32_init_hw() error: we previously assumed 'dc->clk_mgr' could be null (see line 782)
