Linux Distros Unpatched Vulnerability : CVE-2026-80353

high Nessus Plugin ID 370262

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.

- Time-of-check time-of-use (TOCTOU) race condition vulnerability in Apache Tomcat when creating unix domain sockets for the APR/Native connector allows an unauthorised local user to access the unix domain socket.
The fix for CVE-2026-65183 only addressed the NIO connector. It did not address the same issue in the APR/Native connector. This issue affects Apache Tomcat: from 9.0.47 through 9.0.122. Users are recommended to upgrade to version 9.0.123, which fixes the issue. (CVE-2026-80353)

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

Solution

There is no known solution at this time.
