Who should care
Security teams managing Google Chrome on desktops and Android devices, endpoint administrators, browser patch management owners, and SOC teams monitoring browser-exploit risk should prioritize this CVE.
Technical summary
The vulnerability affects Chrome’s V8 JavaScript engine and is described as an incorrect application of type rules that could lead to heap corruption. The NVD classification lists CWE-119. The attack path is remote and browser-based, requiring a user to visit a crafted HTML page. The supplied record also includes Chrome version remediation context and vendor references to a Chrome stable-channel update and related advisories.
Defensive priority
High. This is a remotely reachable browser-engine memory corruption flaw with high confidentiality, integrity, and availability impact, even though user interaction is required.
Recommended defensive actions
- Upgrade Google Chrome to the vendor-fixed releases referenced in the advisory trail.
- Confirm patch coverage across Mac, Windows, Linux, and Android Chrome deployments.
- Prioritize remediation on systems where browser use is common or where users may access untrusted web content.
- Validate that enterprise update channels and mobile management policies are enforcing the corrected Chrome versions.
- Review browser crash or instability signals as a general post-patch hygiene check, without relying on them as detection evidence.
Evidence notes
Primary evidence comes from the NVD CVE record and its embedded Google-sourced references. The CVE description states that V8 in Google Chrome incorrectly applied type rules, enabling potential heap corruption via a crafted HTML page, and the CVSS vector confirms network attackability with required user interaction. The reference set includes Google Chrome stable-channel release notes, a Chromium bug link, and third-party advisories (Red Hat, SecurityFocus, SecurityTracker, Gentoo) supporting that this was a public browser vulnerability with vendor remediation. Note: the supplied NVD CPE criteria end at 54.0.2840.87, while the prose description lists later fixed builds for different platforms; this versioning detail should be treated cautiously and cross-checked against the vendor advisory trail.
