Summary
Samsung Exynos 1480 and Exynos 2400 processors, before November 2026, contain improper input validation in the ENN NeuralNetworks HAL during request processing. This can cause memory corruption, classified as an out-of-bounds write (CWE-787), leading to a denial of service condition. The sources do not describe the attacker's required access or any exploitation activity.
