The software attempts to unlock a resource that is not locked.
Depending on the locking functionality, an unlock of a non-locked resource might cause memory corruption or other modification to the resource (or its associated metadata that is used for tracking locks).
Technical Impact: DoS: crash / exit /
restart; Execute unauthorized code or
commands; Modify memory; Other
Depending on the locking being used, an unlock operation might not
have any adverse effects. When effects exist, the most common
consequence will be a corruption of the state of the software, possibly
leading to a crash or exit; depending on the implementation of the
unlocking, memory corruption or code execution could occur.
