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
Red Hat Product Security issued an advisory for Python 3.12 in Red Hat Enterprise Linux 9.4 and related distributions addressing two vulnerabilities: CVE-2026-6100, a use-after-free in decompression modules that can cause arbitrary code execution or information disclosure, and CVE-2026-4786, a command injection vulnerability in the webbrowser.open() API that allows arbitrary code execution. These vulnerabilities are rated as having a high security impact. Updated python3.12 packages are available from Red Hat to remediate these issues. The advisory references Red Hat Bugzilla entries BZ-2457932 and BZ-2458049 for the respective CVEs and provides package updates for multiple architectures and variants of Red Hat Enterprise Linux 9.4.
Potential Impact
Successful exploitation of CVE-2026-6100 could allow an attacker to execute arbitrary code or disclose sensitive information due to a use-after-free vulnerability in decompression modules. CVE-2026-4786 could enable arbitrary code execution via command injection in the webbrowser.open() API. Both vulnerabilities pose a high security risk to affected systems running vulnerable Python 3.12 versions on Red Hat Enterprise Linux 9.4 and related products.
Mitigation Recommendations
Red Hat has released updated python3.12 packages that address these vulnerabilities. Users of affected Red Hat Enterprise Linux 9.4 and related distributions should apply the python3.12 security update as described in the Red Hat advisory RHSA-2026:17525 and the update instructions at https://access.redhat.com/articles/11258. Applying these official patches is the recommended remediation. No additional mitigations or workarounds are specified in the advisory.
