CVE-2024-45184

Local service interruption via USAT heap overwrite

Published Oct 11, 2024 · Updated Nov 6, 2024

Heap buffer overflow in USAT on Samsung Exynos chipsets allows local users to interrupt service on affected mobile, wearable, or modem devices. USAT writes beyond the bounds of a heap buffer when handling unspecified input; Samsung has not disclosed the faulty function or triggering data. Exploitation requires local access and causes denial of service without reported confidentiality or integrity impact.
