Linux Distros Unpatched Vulnerability : CVE-2026-114690

medium Nessus Plugin ID 374115

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 GCC. An out-of-bounds memory access vulnerability exists in the libstdc++ parallel search implementation due to an undersized internal buffer. A local attacker can exploit this flaw by providing crafted search data to an application compiled with parallel mode, causing the process to crash and leading to a Denial of Service (DoS). (CVE-2026-114690)

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

Solution

There is no known solution at this time.
