CVE-2024-46920Network attack vector

Memory corruption via unchecked input-buffer length

Published Jan 13, 2025 · Updated Jan 13, 2025

A stack out-of-bounds write in Samsung Exynos mobile processors allows remote attackers to corrupt memory via crafted input buffers. The loadInputBuffers function uses an attacker-controlled input-buffer length without checking it against the destination stack buffer. Network access without authentication is sufficient; exploitation can alter or disclose limited data, with no reported service interruption.
