Kernel availability interruption via unchecked sensor bounds
Published Oct 14, 2022 · Updated May 14, 2025
Buffer overflow in the Unisoc sensor driver allows local users to interrupt kernel availability through an out-of-bounds write. The driver omits a bounds check before writing to a memory buffer, but Unisoc has not disclosed the affected function or attacker-controlled input. Exploitation requires high privileges and user interaction on a device using an affected Unisoc chipset; the vendor does not specify whether the denial of service is a hang or crash.
