HIGH 7.4

DescriptionNVD

Concurrent execution using shared resource with improper synchronization ('race condition') in Capability Access Management Service (camsvc) allows an unauthorized attacker to elevate privileges locally.

Analysis

Technical ContextAI

A race condition occurs when the behavior of software depends on the timing of events, such as the order of execution of threads or processes.

RemediationAI

Use proper synchronization mechanisms (locks, mutexes, atomic operations). Implement file locking for filesystem operations. Avoid TOCTOU patterns.
