CVE-2026-2297

Publication date 5 March 2026

Last updated 5 March 2026

Ubuntu priority

Medium

Why this priority?

Description

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.
