CVE-2026-68360

Local system crash via probe teardown race

Published Aug 10, 2026 · Updated Aug 10, 2026

Use-after-free in Linux's corsair-cpro hwmon driver allows local users to crash affected kernels during a failed device probe. The probe error path calls hid_hw_stop() without first stopping device I/O, allowing hid_input_report() to race with teardown and access freed driver state. Reachability requires Corsair Commander Pro hardware, the corsair_cpro module, and a probe failure after device I/O starts; the bounded reported impact is a local system crash.
