The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - NFC: pn533: bound the UART receive buffer pn532_receive_buf() appends every incoming byte to dev->recv_skb     and only resets the buffer after pn532_uart_rx_is_frame() recognizes a complete frame. A continuous stream     of bytes without a valid PN532 frame header therefore keeps growing the skb until skb_put_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 PN532_UART_SKB_BUFF_LEN. (CVE-2026-43032)

Note that Nessus relies on the presence of the package as reported by the vendor.
