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

  - Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime's     implementation of transcoding strings between components contains a bug where the return value of a guest     component's realloc is not validated before the host attempts to write through the pointer. This enables a     guest to cause the host to write arbitrary transcoded string bytes to an arbitrary location up to 4GiB     away from the base of linear memory. These writes on the host could hit unmapped memory or could corrupt     host data structures depending on Wasmtime's configuration. Wasmtime by default reserves 4GiB of virtual     memory for a guest's linear memory meaning that this bug will by default on hosts cause the host to hit     unmapped memory and abort the process due to an unhandled fault. Wasmtime can be configured, however, to     reserve less memory for a guest and to remove all guard pages, so some configurations of Wasmtime may lead     to corruption of data outside of a guest's linear memory, such as host data structures or other guests's     linear memories. This vulnerability is fixed in 24.0.7, 36.0.7, 42.0.2, and 43.0.1. (CVE-2026-35195)

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