Operationally, exploitation aligns with the MITRE ATT&CK technique LSA Secrets (T1003.004); ranked in the top 0.9% 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 CVE-2018-6065 is an integer overflow (CWE-190) in the V8 JavaScript engine in Google Chrome versions prior to 65.0.3325.146. It occurs specifically when computing the required allocation size for instantiating a new JavaScript object and is rated 8.8 on CVSS 3.1 with a vector of AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.

A remote attacker can exploit the flaw by delivering a crafted HTML page that triggers the integer overflow, resulting in heap corruption that may be leveraged for arbitrary code execution or other impacts on the affected browser process.

Vendor references, including the Chrome stable channel update, Red Hat RHSA-2018:0484, and Debian DSA-4182, indicate that the issue is resolved by upgrading to Chrome 65.0.3325.146 or later. The associated Chromium bug report provides additional technical context on the root cause in V8 allocation logic.
