Summary

CVE-2019-5825 is a medium-severity Out-of-bounds Write (CWE-787) vulnerability in Google Chrome. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 1.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

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

The vulnerability is an out-of-bounds write issue in the JavaScript engine of Google Chrome versions prior to 73.0.3683.86, tracked under CWE-787. It resides in JavaScript handling and can result in heap corruption when processing specially crafted input.

A remote attacker can exploit the flaw by serving a crafted HTML page to a victim. With network attack vector, no required privileges, and only user interaction via page rendering, successful exploitation can achieve high-impact denial of service through heap corruption, though confidentiality and integrity impacts are not indicated by the CVSS vector.

Advisories in the Chrome stable channel update for desktop dated April 30, 2019, and the associated Chromium bug tracker entry indicate that updating to version 73.0.3683.86 or later resolves the issue. Public references also include a proof-of-concept demonstrating Array.map corruption in Chrome 72 and 73 builds.
