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. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Winch     compiler contains a bug where a 64-bit table, part of the memory64 proposal of WebAssembly, incorrectly     translated the table.size instruction. This bug could lead to disclosing data on the host's stack to     WebAssembly guests. The host's stack can possibly contain sensitive data related to other host-originating     operations which is not intended to be disclosed to guests. This bug specifically arose from a mistake     where the return value of table.size was statically typed as a 32-bit integer, as opposed to consulting     the table's index type to see how large the returned register could be. When combined with details about     Wnich's ABI, such as multi-value returns, this can be combined to read stack data from the host, within a     guest. This vulnerability is fixed in 36.0.7, 42.0.2, and 43.0.1. (CVE-2026-34945)

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