A local non-privileged user can make improper GPU memory processing operations to gain access to already freed memory.

Arm Mali GPU Kernel Driver allows a non-privileged user to achieve write access to read-only memory pages. This affects Midgard r26p0 through r31p0, Bifrost r0p0 through r35p0, and Valhall r19p0 through r35p0.

. The Arm Mali GPU kernel driver allows an unprivileged user to achieve access to freed memory, leading to information disclosure or root privilege escalation. This affects Bifrost r16p0 through r29p0 before r30p0, Valhall r19p0 through r29p0 before r30p0, and Midgard r28p0 through r30p0.
