CVE-2023-48346

Service interruption via undisclosed decoder input validation

Published Jan 18, 2024 · Updated Jun 20, 2025

Improper input validation in the UNISOC video decoder on affected chipsets running Android 11 or 12 allows local users to interrupt service. UNISOC identifies the video decoder but does not disclose the input field, validation error, malformed-data path, or precise failure mode. Local low-privileged access is required, and the documented consequence is limited to availability loss rather than data disclosure or modification.
