"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: mcp2221: stop device IO before hid_hw_stop\n\nQuiesce device IO at the start of the devm cleanup callback\nmcp2221_hid_unregister() so that incoming HID reports cannot race with\nhardware teardown during probe failure or device removal, addressing a\npotential use-after-free.\n\nGuard the call to hid_device_io_stop() with io_started. On normal\nremoval hid_device_remove() has already cleared io_started before the\ndevres group is released, so an unconditional call would otherwise hit\nthe !io_started path and emit a spurious \"io already stopped\" warning\non every removal. The guard preserves the probe-failure balancing,\nwhere io_started is still set after hid_device_io_start(), while\nstaying silent on the normal removal path."
