Local denial of service via out-of-bounds camera write
Published May 9, 2023 · Updated Jan 29, 2025
An out-of-bounds write in the UNISOC camera driver allows local users with System privileges to interrupt service through a local operation. The driver omits a bounds check before a write, allowing that operation to extend beyond its intended buffer. System-level execution privileges are required, and the documented consequence is local denial of service rather than data disclosure or modification.
