Description

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause race condition in hardware performance counters buffer’s destruction path leading to read and/or write UAF. The race condition in the destruction path could lead to reference counter being decremented in non-atomical way allowing other code paths using a freed object to read and/or write kernel heap memory.

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
