Summary
nfc: pn533: purge fragmented skbs during cleanup
Details

In the Linux kernel, the following vulnerability has been resolved:

nfc: pn533: purge fragmented skbs during cleanup

pn53xcommonclean() purges respq before freeing the common PN533 state, but it leaves fragmentskb 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 fragmentskb during cleanup alongside respq.
