Weakness Name
Unlock of a Resource that is not Locked
Description
The product 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).
Common Consequences
- Scope:
- Integrity, Confidentiality, Availability, Other
- Impact:
- DoS: Crash, Exit, or Restart, Execute Unauthorized Code or Commands, Modify Memory, Other
- Notes:
- 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 product, possibly leading to a crash or exit; depending on the implementation of the unlocking, memory corruption or code execution could occur.
