CVE-2023-42563

Heap overflow via integer overflow in landmarkCopyImageToNative

Published Dec 5, 2023 · Updated Aug 2, 2024

Integer overflow in Samsung Mobile Devices running Android 12 through 14 allows attackers to trigger a heap overflow. The landmarkCopyImageToNative function in libFacePreProcessingjni.camera.samsung.so fails to prevent an integer calculation from overflowing during native image processing. Local exploitation requires low privileges and user interaction; Samsung has not disclosed the attacker-controlled input or any consequence beyond heap corruption.
