What to do
AI-suggested
A fix has been implemented in the Linux kernel source code to free the BO array properly. Users should update to the fixed kernel version once it is released. No other mitigation is indicated.
Description
A memory leak vulnerability in the Linux kernel's drm/vc4 driver was fixed. The issue involved a buffer object (BO) array allocated during a hang state that was not properly freed, leading to a memory leak.
