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

Note that Nessus has not tested for these issues 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.

  - A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard     memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker     could potentially use timing measurements of LDAP bind attempts to infer partial hash information, though     practical exploitation is extremely difficult due to PBKDF2 computational overhead. (CVE-2026-15041)

Note that Nessus relies on the presence of the package as reported by the vendor.
