"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: gs_usb: gs_usb_receive_bulk_callback(): unanchor URL on usb_submit_urb() error\n\nIn commit 7352e1d5932a (\"can: gs_usb: gs_usb_receive_bulk_callback(): fix\nURB memory leak\"), the URB was re-anchored before usb_submit_urb() in\ngs_usb_receive_bulk_callback() to prevent a leak of this URB during\ncleanup.\n\nHowever, this patch did not take into account that usb_submit_urb() could\nfail. The URB remains anchored and\nusb_kill_anchored_urbs(&parent->rx_submitted) in gs_can_close() loops\ninfinitely since the anchor list never becomes empty.\n\nTo fix the bug, unanchor the URB when an usb_submit_urb() error occurs,\nalso print an info message."
