Device compromise via out-of-bounds SIM command access
Published Jul 9, 2024 · Updated Oct 25, 2024
Heap out-of-bounds access in Samsung Exynos processors and modems allows local users to read, alter, or crash the device via a SIM command. The SIM Proactive Command handler accesses beyond the bounds of a heap buffer when processing an unspecified command value; Samsung has not published the responsible function or validation error. Exploitation requires local access but no privileges or user interaction, and the reported consequences include disclosure, modification, and service interruption.
