Description
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix memory leak of BO array in hang state The hang state's BO array is allocated separately with kzalloc() in vc4_save_hang_state() but never freed in vc4_free_hang_state(). Add the missing kfree() for the BO array before freeing the hang state struct.
