CVE-2023-52348

Local denial of service via missing bounds check

Published Apr 8, 2024 · Updated Nov 19, 2024

Out-of-bounds write in UNISOC RIL service on affected Android chipsets allows local users to interrupt service through crafted input. The service writes beyond an intended buffer because it fails to validate a boundary before processing the input. Reachability requires local System execution privileges; published evidence identifies denial of service but does not specify whether the service hangs, crashes, or restarts.
