Local service interruption via unchecked memory write
Published Jul 12, 2023 · Updated Nov 27, 2024
Out-of-bounds write in the UNISOC iwnpi server on Android 10 through Android 13 allows local users to interrupt its service. The server performs a memory write without the required bounds check, permitting the write to extend beyond its intended buffer; UNISOC has not disclosed the affected function or input path. Only listed UNISOC chipsets are affected, and exploitation requires local access with System execution privileges; the failure mode is undisclosed.
