There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2026-72712)

The AlmaLinux 9.6 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1789630245 advisory.

  - 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. (CVE-2026-72712)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the nmap packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    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.(CVE-2026-72712)

Tenable has extracted the preceding description block directly from the EulerOS nmap security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
