Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 6.8. It stems from pvrvmgpuvaremap within drm/imagination failing to release GEM references obtained from split parts when remapping occurs. These split parts are then incorrectly linked to vmbo of a new object, resulting in reference leaks...
