CVE-2024-49916

Description

In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn401_init_hwThis commit addresses a potential null pointer dereference issue in thedcn401_init_hw function. The issue could occur when dc->clk_mgr ordc->clk_mgr->funcs is null.The fix adds a check to ensure dc->clk_mgr and dc->clk_mgr->funcs isnot null before accessing its functions. This prevents a potential nullpointer dereference.Reported by smatch:drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:416 dcn401_init_hw() error: we previously assumed 'dc->clk_mgr' could be null (see line 225)
