HIGH 7.8
Description
Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery.
Analysis
Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery.
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: Arm Mbed Tls
Remediation
Use proper synchronization mechanisms (locks, mutexes, atomic operations). Implement file locking for filesystem operations. Avoid TOCTOU patterns.
