Arm Mali GPU Kernel Driver has a use-after-free: Midgard r28p0 through r29p0 before r30p0, Bifrost r17p0 through r23p0 before r24p0, and Valhall r19p0 through r23p0 before r24p0.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
