Linux Distros Unpatched Vulnerability : CVE-2026-127030

critical Nessus Plugin ID 379992

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 freeradius. An improper length validation in the EAP-FAST module allows a stack-based buffer overflow during session ticket processing. A remote, unauthenticated attacker can exploit this flaw by sending a specially crafted handshake request, causing the server process to crash and resulting in a Denial of Service (DoS). (CVE-2026-127030)

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

Solution

There is no known solution at this time.
