Linux Distros Unpatched Vulnerability : CVE-2026-107167

medium Nessus Plugin ID 363912

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 flaw was found in m17n-lib. A user providing specially crafted text input can trigger a heap use-after- free condition during input-method state transitions. Under specific conditions, the library frees an internal input context object but subsequently attempts to write to that freed memory. This issue can cause applications relying on the library to crash, leading to a Denial of Service (DoS), or potentially allow arbitrary code execution. (CVE-2026-107167)

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

Solution

There is no known solution at this time.
