In the Linux kernel, the following vulnerability has been resolved: nfc: pn533: purge fragmented skbs during cleanup pn53x_common_clean() purges resp_q before freeing the common PN533 state, but it leaves fragment_skb untouched. The fragmentation helpers queue transmit fragments there while sending large initiator or target-mode frames, and those skbs remain owned by the driver until they are sent or discarded. If the device is removed while fragments are still queued, the common cleanup path frees the PN533 state without releasing the queued fragment skbs, leaking them. Purge fragment_skb during cleanup alongside resp_q.
