  3. CVE-2022-49729
In the Linux kernel, the following vulnerability has been resolved: nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred Similar to the handling of play_deferred in commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought a patch might be needed here as well. Currently usb_submit_urb is called directly to submit deferred tx urbs after unanchor them. So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb and cause memory leak. Put those urbs in tx_anchor to avoid the leak, and also fix the error handling.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred De forma similar a la gestión de play_deferred en el commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in play_deferred"), pensamos que también podría ser necesario un parche aquí. Actualmente, se llama a usb_submit_urb directamente para enviar urbs de tx diferidas después de desanclarlas. Por lo tanto, usb_giveback_urb_bh no podría desreferenciarla en usb_unanchor_urb y provocaría una pérdida de memoria. Coloque esas urbs en tx_anchor para evitar la pérdida y también corrija la gestión de errores.
