CVE-2025-71158Hinoki check available

Local system crash via unterminated IRQ worker

Published Jan 23, 2026 · Updated Jan 23, 2026

Race condition in the Linux Kernel GPIO MPSSE driver 6.13 through 6.18.5 allows local users to crash the system during device disconnect. The disconnect path releases device state without synchronously canceling the polling work item, allowing the worker to continue after teardown. Reachability requires access to an MPSSE-backed GPIO device with edge detection armed and a concurrent software or physical disconnect; successful triggering crashes the kernel.
