Mitigating Controls (NIST 800-53 r5) AI

prevent

Memory protection directly counters double-free conditions arising from the race in the issimian driver.

prevent

Process isolation limits the blast radius of a driver-level race condition to the affected Exynos component.

prevent

Denial-of-service protection mechanisms can throttle or contain the resource-exhaustion outcome of the double-free.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

detects

Security testing can detect race conditions, but does not prevent them at design or coding time.

prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

prevents

Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.

prevents

Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.

none

Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
