Linux Distros Unpatched Vulnerability : CVE-2026-119132

medium Nessus Plugin ID 374100

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.

 - Wasmtime from 49.0.0 before 49.0.3 contains a denial-of-service vulnerability that allows a WebAssembly guest to trigger a host panic by transcoding overlapping strings in fused adapters. Attackers can make a same-instance component-to-component call transferring a string whose source and destination alias each other, crashing the host instead of raising a trap. (CVE-2026-119132)

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

Solution

There is no known solution at this time.
