      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nNFC: pn533: bound the UART receive buffer\n\npn532_receive_buf() appends every incoming byte to dev->recv_skb and\nonly resets the buffer after pn532_uart_rx_is_frame() recognizes a\ncomplete frame. A continuous stream of bytes without a valid PN532 frame\nheader therefore keeps growing the skb until skb_put_u8() hits the tail\nlimit.\n\nDrop the accumulated partial frame once the fixed receive buffer is full\nso malformed UART traffic cannot grow the skb past\nPN532_UART_SKB_BUFF_LEN.",
