CVE-2026-5713  (opens in a new tab)

How to fix?

Upgrade Debian:unstable python3.14 to version 3.14.5-1 or higher.

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 Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The "profiling.sampling" module (Python 3.15+) and "asyncio introspection capabilities" (3.14+, "python -m asyncio ps" and "python -m asyncio pstree") features could be used to read and write addresses in a privileged process if that process connected to a malicious or "infected" Python process via the remote debugging feature. This vulnerability requires persistently and repeatedly connecting to the process to be exploited, even after the connecting process crashes with high likelihood due to ASLR.
