CVE-2023-48358

Local service interrupt via unchecked DRM driver write

Published Jan 18, 2024 · Updated Jun 20, 2025

An out-of-bounds write in the DRM driver for affected Unisoc chipsets on Android 11 through Android 13 allows local users to interrupt service. The driver performs a write without checking the destination bounds; Unisoc has not disclosed the affected function, input, or trigger path. Triggering the flaw requires System-level execution privileges, and no remote path or more specific denial-of-service behavior is reported.
