CVE-2023-53533

Service interruption via touchscreen probe reference leak

Published Oct 4, 2025 · Updated Oct 4, 2025

Resource leak in the Linux kernel raspberrypi-ts driver from 5.0 allows local users to interrupt service through failed device probes. In rpi_ts_probe, error returns after rpi_firmware_get leave acquired firmware references unreleased because cleanup does not cover those paths. The driver and Raspberry Pi firmware touchscreen hardware must be present; public records do not identify how an unprivileged user forces repeated probe failures.
