Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Use after free in Blink in Google Chrome prior to 77.0.3865.90 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Use-after-free vulnerability in Blink, Google's rendering engine for Chrome. A remote attacker could exploit heap corruption by tricking users into visiting a crafted HTML page, potentially leading to arbitrary code execution.

MitigationUpdate Google Chrome to version 77.0.3865.90 or later. Until patched, avoid visiting untrusted websites and consider using an alternative browser for high-risk web browsing.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine installed Chrome version
    Navigate to chrome://settings/help or click the three-dot menu > Settings > About Chrome to view the current version number
    Affected if version number is less than 77.0.3865.90
  2. Confirm Chrome is using Blink engine
    Chrome uses the Blink rendering engine by default. No manual verification needed for standard Chrome installations
    Affected if Chrome is the default configuration (Blink is always used in Chrome)
  3. Assess web browsing exposure
    Determine whether the browser is used to access web content. This vulnerability is exploitable when a user visits a specially crafted HTML page
    Affected if users browse untrusted or malicious websites using the affected Chrome version

User is affected if Chrome version is below 77.0.3865.90 AND the browser is used to visit web pages, since the vulnerability triggers through rendered HTML content
