Summary

CVE-2017-5030 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Google Chrome. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 1% 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 read (CWE-125) stemming from incorrect handling of complex species in the V8 JavaScript engine. It affects Google Chrome versions prior to 57.0.2987.98 on Linux, Windows, and Mac, and prior to 57.0.2987.108 on Android, and carries a CVSS 3.1 base score of 8.8.

A remote attacker can exploit the flaw by serving a specially crafted HTML page that triggers the mishandling in V8. Successful exploitation grants arbitrary code execution in the context of the renderer process, with the attack vector requiring user interaction such as visiting a malicious site.

Vendor advisories, including the Chrome stable channel update, Red Hat RHSA-2017-0499, and Debian DSA-3810, direct users to upgrade to the fixed releases listed above; the corresponding Chromium bug report (682194) provides additional technical detail on the patch. No information on observed in-the-wild exploitation is supplied in the references.
