CVE-2024-31959

Code execution via unvalidated native handles

Improper input validation in Samsung Exynos 1480, 2200, and 2400 processors allows local users to execute code through native handles. The mobile processor accepts native handles without performing the required validity check before using them. Local access is required; Samsung has not disclosed the affected subsystem, handle source, execution context, or privileges gained.
