Description

Use After Free vulnerability in Arm Ltd Midgard GPU Kernel Driver, Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user to exploit a software race condition to perform improper memory processing operations. If the system’s memory is carefully prepared by the user and the system is under heavy load, then this in turn cause a use-after-free.This issue affects Midgard GPU Kernel Driver: from r13p0 through r32p0; Bifrost GPU Kernel Driver: from r1p0 through r18p0; Valhall GPU Kernel Driver: from r37p0 through r46p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r46p0.

CWE-416
Use After Free
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
