Summary

CVE-2024-4671 is a critical-severity Use After Free (CWE-416) vulnerability in Fedoraproject Fedora. Its CVSS base score is 9.6 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked in the top 6% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-4671 is a use-after-free vulnerability (CWE-416) in the Visuals component of Google Chrome versions prior to 124.0.6367.201. The flaw resides in the renderer process and carries a CVSS 3.1 score of 9.6, reflecting network attack vectors with low complexity and high impact across confidentiality, integrity, and availability when the sandbox boundary is crossed.

An attacker who has already achieved code execution inside the renderer can supply a specially crafted HTML page that triggers the use-after-free condition, enabling a sandbox escape and potential elevation to higher-privilege execution on the host system. The attack requires user interaction such as visiting a malicious web page but does not require additional privileges beyond renderer compromise.

Public advisories direct users to update to Chrome 124.0.6367.201 or later; corresponding packages have been issued for Fedora and other distributions to address the issue in stable channels.

EPSS scores rose from a low baseline to a peak of 0.0197 on the disclosure date of 14 May 2024 before receding to the current value of 0.0057, indicating transient post-disclosure interest without confirmed in-the-wild exploitation at this time.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover use-after-free bugs through dynamic analysis or fuzzing.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can require memory-safe constructs or languages that structurally avoid introducing use-after-free.

SC-39 Process Isolation partial match

Process isolation confines the blast radius of use-after-free memory corruption to a single execution domain.

SI-16 Memory Protection partial match

Memory protection controls limit exploitation impact by blocking unauthorized code execution from dangling pointers.
