"The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1764322970 advisory.

  - DHCP can add routes to a client's routing table via the classless static route option (121). VPN-based
    security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical
    interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic
    that was expected to be protected by the VPN. (CVE-2024-3661)

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