CVE-2026-23082

In the Linux kernel, the following vulnerability has been resolved:

can: gsusb: gsusbreceivebulkcallback(): unanchor URL on usbsubmit_urb() error

In commit 7352e1d5932a ("can: gsusb: gsusbreceivebulkcallback(): fix URB memory leak"), the URB was re-anchored before usbsubmiturb() in gsusbreceivebulk_callback() to prevent a leak of this URB during cleanup.

However, this patch did not take into account that usbsubmiturb() could fail. The URB remains anchored and usbkillanchoredurbs(&parent->rxsubmitted) in gscanclose() loops infinitely since the anchor list never becomes empty.

To fix the bug, unanchor the URB when an usbsubmiturb() error occurs, also print an info message.
