CVE-2026-80800

CVE-2026-80800 affects the Linux kernel NFC LLCP subsystem. The function nfc_llcp_connect_sn() walks a TLV list without validating that the two-byte header or declared length stay within the skb buffer, and computes tlv_array_len as skb->len - LLCP_HEADER_SIZE in size_t, causing an underflow f...

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...
