Linux Distros Unpatched Vulnerability : CVE-2026-116486

low Nessus Plugin ID 372354

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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

 - Objenesis before 3.6 contains a type confusion vulnerability that allows code in one class loader to substitute objects into another by exploiting instantiator caching keyed on class name. When a shared ObjenesisStd instance caches instantiators by clazz.getName() in ObjenesisBase.getInstantiatorOf(), same- named classes collide, causing newInstance() to return wrong-class objects and ClassCastException failures. (CVE-2026-116486)

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

Solution

There is no known solution at this time.
