  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: atm: cxacru: properly kill rcv_urb on error in cxacru_cm()  If cxacru_cm() encounters an error while submitting or waiting for snd_urb, it aborts and returns the error without killing the already submitted rcv_urb. This leaves the rcv_urb active.  When this happens during initialization (e.g., in cxacru_atm_start()), the driver may ignore the error and proceed to call cxacru_poll_status(), which invokes cxacru_cm() again. Attempting to submit the still-active rcv_urb triggers a warning in usb_submit_urb():  cxacru 1-1:1.0: send of cm 0x84 failed (-104) ATM dev 0: cxacru_atm_start: CHIP_ADSL_LINE_START returned -104 ------------[ cut here ]------------ URB ffff88812658d200 submitted while active WARNING: drivers/usb/core/urb.c:379 at usb_submit_urb+0x79/0x18b0 drivers/usb/core/urb.c:379 ...

To fix this, ensure that rcv_urb is properly killed if cxacru_cm() aborts early. We can safely call usb_kill_urb() on rcv_urb in the error path, as it is safe to call even if the URB is not active (e.g., if it failed to submit in the first place, or if it already completed).",
