    CVE-2026-72712 (GCVE-0-2026-72712)

    Vulnerability from nvd – Published: 2026-08-11 17:35 – Updated: 2026-08-13 14:12

    Title
    Nmap 7.99 Denial of Service via Zero-Length TCP Option Packet
    Summary
    Nmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option. The malformed packet forces the Packet:parse_options() function in nselib/packet.lua to allocate objects in an infinite loop, causing an out-of-memory condition that results in application crash.
