Linux Distros Unpatched Vulnerability : CVE-2026-94370

critical Nessus Plugin ID 365656

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.

- A defect in the Qt for MCUs core string handling causes heap memory corruption. When an application passes text into Qt Quick Ultralite using the public Qul::String interface type, and that text is held in a std::string, the conversion to the internal string type copies the pointer without taking ownership of it.
Two objects then release the same memory, producing a double free, an invalid free, or a use-after-free.
(CVE-2026-94370)

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

Solution

There is no known solution at this time.
