CVE-2026-2297 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:26.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3.14 package and not the python3.14 package as distributed by Ubuntu.
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.
