Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_receive_bulk_callback(): unanchor URL on usb_submit_urb() error In commit 7352e1d5932a ("can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak"), the URB was re-anchored before usb_submit_urb() in gs_usb_receive_bulk_callback() to prevent a leak of this URB during cleanup. However, this patch did not take into account that usb_submit_urb() could fail. The URB remains anchored and usb_kill_anchored_urbs(&parent->rx_submitted) in gs_can_close() loops infinitely since the anchor list never becomes empty. To fix the bug, unanchor the URB when an usb_submit_urb() error occurs, also print an info message.
