Description

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.

• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
