Local processor compromise via unchecked reference counting
Published Jun 7, 2024 · Updated Aug 27, 2025
Use-after-free in Samsung Exynos 850, 1080, 2100, 1280, 1380, 1330, W920, and W930 allows local users to compromise the processor. The mobile processor fails to validate reference counts before ending an object lifetime, so later code can access freed memory through a stale reference. The attack requires local access without prior privileges or user interaction; Samsung has not disclosed whether exploitation causes a crash, code execution, or another concrete outcome.
