CVE-2026-23061

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> can: kvaser_usb: kvaser_usb_read_bulk_callback(): fix URB memory leak<br /> <br /> Fix similar memory leak as in commit 7352e1d5932a ("can: gs_usb:<br /> gs_usb_receive_bulk_callback(): fix URB memory leak").<br /> <br /> In kvaser_usb_set_{,data_}bittiming() -&gt; kvaser_usb_setup_rx_urbs(), the<br /> URBs for USB-in transfers are allocated, added to the dev-&gt;rx_submitted<br /> anchor and submitted. In the complete callback<br /> kvaser_usb_read_bulk_callback(), the URBs are processed and resubmitted. In<br /> kvaser_usb_remove_interfaces() the URBs are freed by calling<br /> usb_kill_anchored_urbs(&amp;dev-&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 usb_kill_anchored_urbs().<br /> <br /> Fix the memory leak by anchoring the URB in the<br /> kvaser_usb_read_bulk_callback() to the dev-&gt;rx_submitted anchor.
