Summary

CVE-2024-4761 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Fedoraproject Fedora. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 5% 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-15 (Development Process, Standards, and Tools) — 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-2024-4761 is an out-of-bounds write vulnerability in the V8 JavaScript engine within Google Chrome versions prior to 124.0.6367.207. The flaw, assigned CWE-787 and rated high severity with a CVSS 3.1 score of 8.8, permits an attacker to corrupt memory outside allocated bounds when processing a specially crafted HTML page.

A remote attacker can trigger the issue by causing a victim to visit a malicious web page, resulting in an out-of-bounds memory write that may allow arbitrary code execution or other impacts affecting confidentiality, integrity, and availability without requiring authentication or user privileges beyond loading the page.

The primary mitigation is to update Google Chrome to version 124.0.6367.207 or later, as noted in the stable channel release announcement; Fedora package maintainers have also issued corresponding updates for affected Linux distributions.

EPSS for the CVE rose from lower values to a peak of 0.1131 on 2026-03-01 before receding to the current 0.0629, indicating a period of increased exploitation interest after disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

SI-10 Information Input Validation partial match

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

PR.PS-06 mostly match
prevents

Secure-development practices (static analysis, bounds checking, code review) are the primary means of preventing out-of-bounds writes.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

prevents

Application security requirements can specify bounds-checking and safe memory handling.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture and engineering principles reduce the likelihood of buffer overflows.

A.8.28 Secure coding partial match
prevents

Secure coding directly addresses out-of-bounds writes through language choice and coding standards.

A.8.32 Change management partial match
prevents

Change management can enforce review gates that catch unsafe memory operations before deployment.
