CVE-2026-58058 Nmap - Integer Underflow in IPv6 Extension Header Parsing

Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6getdataprimitive 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 craft...
