CVE-2026-80799
CVE-2026-80799 affects the Linux kernel NFC LLCP subsystem, specifically the nfc_llcp_parse_gb_tlv() and nfc_llcp_parse_connection_tlv() TLV parsers. Three related bugs exist: (1) an u8 offset that silently wraps to zero when TLV data exceeds 255 bytes, causing infinite loops; (2) a missing bound...

CVE-2026-80798
CVE-2026-80798 affects the Linux kernel NFC LLCP subsystem . The receive path in nfc_llcp_rx_skb() never validated that a frame is at least LLCP_HEADER_SIZE bytes before parsing. When a short frame is received, the computation skb->len - LLCP_HEADER_SIZE underflows (as size_t), causing the TLV...
CVE-2026-80797 nfc: pn533: purge fragmented skbs during cleanup
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 lar...
CVE-2026-80797
CVE-2026-80797 is a memory leak in the Linux kernel NFC PN533 driver. The function pn53x_common_clean() purges resp_q before freeing the common PN533 state but does not release fragment_skb , which holds queued transmit fragments used when sending large initiator or target-mode frames. If the dev...
