CWE-832 对未加锁的资源进行解锁

Unlock of a Resource that is not Locked

结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

The software attempts to unlock a resource that is not locked.

扩展描述

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).

常见的影响

范围 影响 注释
['Integrity', 'Confidentiality', 'Availability', 'Other'] ['DoS: Crash, Exit, or 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.
