What to do
AI-suggested
A fix has been applied in the Linux kernel source code that adds a null check for head_pipe in the affected function. Users should update to the latest Linux kernel version containing this fix once available. No additional mitigation is indicated.
Description
A null pointer dereference vulnerability was identified and fixed in the Linux kernel's AMD GPU display driver component. The issue occurred in the function dcn32_acquire_idle_pipe_for_head_pipe_in_layer when the head_pipe pointer was null. The fix adds a null check to prevent dereferencing a null pointer, which could cause a kernel crash or instability.
