Use-after-free via concurrent sysfs write
Published Sep 4, 2026 · Updated Sep 4, 2026
Use-after-free in the Linux HID sensor custom driver allows local users with sysfs write access to crash the system through an enable_sensor race. During removal, enable_sensor_store can call set_power_report_state after field attributes have been freed, dereferencing stale power_state or report_state pointers. Reaching the fault requires a concurrent local write while the device is removed; the published record identifies no data-disclosure or code-execution effect.
