In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak In gs_can_open(), the URBs for USB-in transfers are allocated, added to the parent->rx_submitted anchor and submitted. In the complete callback gs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In gs_can_close() the URBs are freed by calling usb_kill_anchored_urbs(parent->rx_submitted). However, this does not take into account that the USB framework unanchors the URB before the complete function is called. This means that once an in-URB has been completed, it is no longer anchored and is ultimately not released in gs_can_close(). Fix the memory leak by anchoring the URB in the gs_usb_receive_bulk_callback() to the parent->rx_submitted anchor.
Conclusion & alert: CVE-2026-23031 is rated Low Risk (3.5/100): low exploitation likelihood (EPSS 0.02%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
