    CVE-2026-58058 (GCVE-0-2026-58058)

    Vulnerability from nvd – Published: 2026-06-28 01:32 – Updated: 2026-06-29 14:53
    VLAI
    Title
    Nmap - Integer Underflow in IPv6 Extension Header Parsing
    Summary
    Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6_get_data_primitive (libnetutil/netutil.cc), so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a crafted IPv6 response with a truncated extension header can trigger out-of-bounds reads and a crash during raw IPv6 scans.

    Vulnerability from cvelistv5 – Published: 2026-06-28 01:32 – Updated: 2026-06-29 14:53
    VLAI
    Title
    Nmap - Integer Underflow in IPv6 Extension Header Parsing
    Summary
    Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6_get_data_primitive (libnetutil/netutil.cc), so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a crafted IPv6 response with a truncated extension header can trigger out-of-bounds reads and a crash during raw IPv6 scans.
