"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: scarlett2: Use a private URB for the notification endpoint\n\nscarlett2_init_notify() used mixer->urb, which\nsnd_usb_mixer_status_create() allocates for the UAC2 status interrupt\nendpoint and mixer.c manages. On a device with that endpoint, the\n\"already in use\" check fires on the status URB and returns 0 for\nsuccess without doing anything. No notification URB is submitted, and\ncmd_done is left zeroed because it is initialised past that check and\nnowhere else. scarlett2_usb_init() then issues SCARLETT2_USB_INIT_1\nand wait_for_completion_timeout() would crash adding to the zeroed\nwait.head.\n\nUse a separate URB in scarlett2_data, as done for FCP, and initialise\ncmd_done in scarlett2_init_private(). mixer.c was also freeing the URB\nin snd_usb_mixer_free() and resubmitting it in\nsnd_usb_mixer_activate(), so scarlett2 must now do both: add\nscarlett2_cleanup_urb(), called from private_free and private_suspend,\nand a private_resume callback to re-establish the URB after resume.\nscarlett2_init_notify() is reached from there, and the URB kill path\nin scarlett2_notify() completes cmd_done, leaving a stale count that\nwould satisfy the next command's wait before the device ACKs. Use\nreinit_completion() to clear it.\n\nAlso free the URB if the transfer buffer allocation fails, and both if\nusb_submit_urb() fails. Move scarlett2_init_notify() up next to\nscarlett2_cleanup_urb() so scarlett2_init_private() can reference it\nwithout a forward declaration."
