The fix for CVE-2026-41409 was not applied to the 2.1.X and 2.2.X branches. Here was the original issue description: The fix for CVE-2024-52046 in Apache MINA AbstractIoBuffer.getObject() was incomplete. The classname allowlist of classes allowed to be deserialized was applied too late after a static initializer in a class to be read might already have been executed. Affected versions are Apache MINA 2.1.0 <= 2.1.11, and 2.2.0 <= 2.2.6. The problem is resolved in Apache MINA 2.1.12, and 2.2.7 by applying the classname allowlist earlier.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8465-1 advisory.

    It was discovered that Apache MINA lacked an acceptMatchers allowlist mechanism to restrict which classes     could be deserialized. An attacker could use this to execute arbitrary code. This issue only affected     Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-52046)

    It was discovered that Apache MINA's deserialization filter could be bypassed via multiple code paths. An     attacker could use this to execute arbitrary code by sending a specially crafted serialized object over     the network. (CVE-2026-42778, CVE-2026-42779, CVE-2026-47065)

Tenable has extracted the preceding description block directly from the Ubuntu 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.
