Arm Mali GPU Kernel Driver Use-After-Free Vulnerability

The Arm Mali GPU kernel driver allows unprivileged users to access freed memory because GPU memory operations are mishandled. This affects Bifrost r0p0 through r38p1, and r39p0; Valhall r19p0 through r38p1, and r39p0; and Midgard r4p0 through r32p0.

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Google Android ausnutzen, um seine Privilegien zu erhöhen, vertrauliche Informationen offenzulegen, Code auszuführen und einen Denial-of-Service-Zustand zu verursachen.
ASB-A-2596959582023-04-01vendor · osvUS
In kbase_mem_flags_change of mali_kbase_mem_linux.c, there is a possible way to corrupt memory due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
