Summary
NFC: pn533: bound the UART receive buffer
Details

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

NFC: pn533: bound the UART receive buffer

pn532receivebuf() appends every incoming byte to dev->recvskb and only resets the buffer after pn532uartrxisframe() recognizes a complete frame. A continuous stream of bytes without a valid PN532 frame header therefore keeps growing the skb until skbput_u8() hits the tail limit.

Drop the accumulated partial frame once the fixed receive buffer is full so malformed UART traffic cannot grow the skb past PN532UARTSKBBUFFLEN.
