Analysis

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

Technical Context

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.

Affected Products

Affected products: Microsoft Windows 10 1809, Microsoft Windows 10 21H2, Microsoft Windows 10 22H2, Microsoft Windows 11 22H2

Remediation

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