CVE-2023-48350Network attack vector

Remote service crash via unchecked decoder write

Published Jan 18, 2024 · Updated Jun 20, 2025

An out-of-bounds write in UNISOC video decoders on Android 11 and 12 chipsets allows remote attackers to crash the decoding service. The decoder performs a write without checking the destination bounds, allowing crafted input to overwrite memory beyond the intended buffer. No authentication or user interaction is required; the documented consequence is a service interruption rather than data disclosure or modification.
