Amazon Linux 2023 : python3.14, python3.14-devel, python3.14-freethreading (ALAS2023-2026-1674)

medium Nessus Plugin ID 315647

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1674 advisory.

 The import hook in CPython that handles legacy *.pyc files (SourcelessFileLoader) is incorrectly handled in FileLoader (a base class) and so does not use io.open_code() to read the .pyc files. sys.audit handlers for this audit event therefore do not fire. (CVE-2026-2297)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update python3.14 --releasever 2023.11.20260511' or or 'dnf update --advisory ALAS2023-2026-1674 --releasever 2023.11.20260511' to update your system.
