Use After Free (UAF) vulnerability in the uinput module.Successful exploitation of this vulnerability may lead to kernel privilege escalation.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
