{"id":"DEBIAN-CVE-2026-68361","details":"In the Linux kernel, the following vulnerability has been resolved:  hwmon: (corsair-psu) Stop device IO before calling hid_hw_stop  hid_hw_stop() does not stop the device IO.  This results in a race condition between hid_input_report() and the point immediately following the execution of hid_device_io_start() within corsairpsu_probe(). If the probe operation fails after \"io start\" has been initiated, this race condition will result in a uaf vulnerability [1].  CPU0\t\t\t\tCPU1 ====\t\t\t\t==== corsairpsu_probe()  hid_device_io_start()   ... unlock driver_input_lock  hid_hw_stop()   kfree(hidraw)\t\t\t__hid_input_report() \t\t\t\t ... acquire driver_input_lock \t\t\t\t hid_report_raw_event() \t\t\t\t  hidraw_report_event() \t\t\t\t   ... access hidraw's list_lock // trigger uaf  Consequently, when corsairpsu_probe() fails and hid_hw_stop() needs to be executed, the io_started flag is first cleared while holding the driver_input_lock to prevent potential race conditions involving input reports.
