Use After Free in Arm Mali GPU Kernel Driver
CVE-2023-34970
A local non-privileged user can make improper GPU processing operations to access a limited amount outside of buffer bounds or to exploit a software race condition. If the system’s memory is carefully prepared by the user, then this in turn could give them access to already freed memory
