critical Nessus Plugin ID 344766

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.

Malformed file-sharing transaction packets with mismatched header lengths allow incoming data to spill out of designated network buffers, risking localized memory corruption. (CVE-2026-57228)

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