Red Hat Security Advisory: python3.12 security update
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * python: Python: Arbitrary code execution or information disclosure via use-after-free in decompression modules (CVE-2026-6100) * python: cpython: Python: Arbitrary code execution via command injection in webbrowser.open() API (CVE-2026-4786) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Technical Summary
This advisory covers two security flaws in Python 3.12 as packaged by Red Hat for Enterprise Linux 10. CVE-2026-6100 is a use-after-free vulnerability in decompression modules that may allow arbitrary code execution or information disclosure. CVE-2026-4786 is a command injection vulnerability in the webbrowser.open() API that could lead to arbitrary code execution. Red Hat has released updated python3.12 packages to address these issues across multiple architectures and product variants. The advisory references Red Hat's errata RHSA-2026:10711 for detailed remediation instructions.
Potential Impact
Successful exploitation of CVE-2026-6100 could result in arbitrary code execution or information disclosure due to a use-after-free condition in decompression modules. CVE-2026-4786 could allow an attacker to execute arbitrary commands via the webbrowser.open() API. Both vulnerabilities pose a high security risk to affected systems running vulnerable Python versions. No public exploits have been reported yet.
Mitigation Recommendations
Red Hat has released updated python3.12 packages that fix these vulnerabilities. Users of affected Red Hat Enterprise Linux 10 variants should apply the security update as described in Red Hat advisory RHSA-2026:10711 and the referenced article https://access.redhat.com/articles/11258. Applying these official patches is the recommended remediation. There is no indication that additional mitigation steps are required beyond applying the update.
