CVE-2026-23031

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak<br /> <br /> In gs_can_open(), the URBs for USB-in transfers are allocated, added to the<br /> parent-&gt;rx_submitted anchor and submitted. In the complete callback<br /> gs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In<br /> gs_can_close() the URBs are freed by calling<br /> usb_kill_anchored_urbs(parent-&gt;rx_submitted).<br /> <br /> However, this does not take into account that the USB framework unanchors<br /> the URB before the complete function is called. This means that once an<br /> in-URB has been completed, it is no longer anchored and is ultimately not<br /> released in gs_can_close().<br /> <br /> Fix the memory leak by anchoring the URB in the<br /> gs_usb_receive_bulk_callback() to the parent-&gt;rx_submitted anchor.
