Description

Use After Free vulnerability in 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 make improper GPU memory processing operations to gain access to already freed memory.This issue affects Bifrost GPU Kernel Driver: from r43p0 through r49p0; Valhall GPU Kernel Driver: from r43p0 through r49p0; Arm 5th Gen GPU Architecture Kernel Driver: from r43p0 through r49p0.

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
