CVE-2022-47488

Local service interruption via unchecked spipe write

Published May 9, 2023 · Updated Jan 28, 2025

Out-of-bounds write in the UNISOC spipe driver on Android 10 through 13 allows local users with System privileges to interrupt service. The kernel driver writes beyond a memory-buffer boundary because its write path lacks a bounds check; UNISOC has not identified the buffer or function. The documented consequence is local denial of service, but public material does not specify whether the interruption is a crash, hang, or reboot.
