What to do
AI-suggested
A fix has been applied to the Linux kernel to address this memory leak by ensuring proper memory deallocation in the error path. Users should update to the fixed kernel version once available. No additional mitigation is required beyond applying the official patch.
Description
A memory leak vulnerability in the Linux kernel's drm/vc4 component was fixed. The issue occurred when the function vc4_save_hang_state() returned early without freeing allocated memory, leading to a leak. The fix consolidates early return paths to ensure proper memory deallocation.
