Arm Mali GPU Kernel Driver (Midgard r4p0 through r31p0, Bifrost r0p0 through r36p0 before r37p0, and Valhall r19p0 through r36p0 before r37p0) allows improper GPU memory operations to reach a use-after-free situation.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
