CVE-2026-68361

System crash via corsair-psu probe race

Published Aug 10, 2026 · Updated Aug 10, 2026

Use-after-free in the Linux corsair-psu driver allows physically proximate attackers to crash affected systems during failed device probing. The corsairpsu_probe() failure path calls hid_hw_stop() without first stopping device I/O, so a concurrent HID input report accesses the freed hidraw list lock. Exploitation requires a supported USB HID power supply and a probe failure after I/O starts; a crash is demonstrated, while code execution is not.
