  3. CVE-2026-23082
In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_receive_bulk_callback(): unanchor URL on usb_submit_urb() error In commit 7352e1d5932a ("can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak"), the URB was re-anchored before usb_submit_urb() in gs_usb_receive_bulk_callback() to prevent a leak of this URB during cleanup. However, this patch did not take into account that usb_submit_urb() could fail. The URB remains anchored and usb_kill_anchored_urbs(&parent->rx_submitted) in gs_can_close() loops infinitely since the anchor list never becomes empty. To fix the bug, unanchor the URB when an usb_submit_urb() error occurs, also print an info message.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: can: gs_usb: gs_usb_receive_bulk_callback(): desanclar URL en error de usb_submit_urb() En el commit 7352e1d5932a ("can: gs_usb: gs_usb_receive_bulk_callback(): corregir fuga de memoria de URB"), el URB fue re-anclado antes de usb_submit_urb() en gs_usb_receive_bulk_callback() para prevenir una fuga de este URB durante la limpieza. Sin embargo, este parche no tuvo en cuenta que usb_submit_urb() podría fallar. El URB permanece anclado y usb_kill_anchored_urbs(&parent->rx_submitted) en gs_can_close() entra en un bucle infinito ya que la lista de anclajes nunca queda vacía. Para corregir el error, desanclar el URB cuando ocurre un error de usb_submit_urb(), también imprimir un mensaje de información.
