CVE-2026-31762

Service interrupt via leaked MPU3050 IRQ handler

Published May 1, 2026 · Updated May 1, 2026

Resource leak in the Linux Kernel MPU3050 gyroscope driver allows local users to cause a service interrupt after registration fails. In mpu3050_trigger_probe(), an iio_trigger_register() failure returns after request_threaded_irq() succeeds without calling free_irq(), leaving the interrupt handler allocated. Reachability requires local low-privileged access, the MPU3050 driver, and failure of trigger registration; the consequence is limited to availability.
