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 UI in Google Chrome prior to 148.0.7778.168 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)

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

This is a use-after-free vulnerability in the Chrome UI component. A remote attacker can exploit this by tricking a user into visiting a crafted HTML page that triggers the use-after-free condition, potentially allowing the attacker to escape the browser sandbox and execute arbitrary code.

MitigationUpdate Google Chrome to version 148.0.7778.168 or later. No configuration-based workarounds exist for use-after-free vulnerabilities; patching is the only effective remediation.

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 in the Chrome browser, or right-click the Chrome shortcut and select 'Properties' to view the version information in the 'Details' tab
    Affected if The displayed version number is lower than 148.0.7778.168
  2. Compare version against vulnerability range
    Compare your installed Chrome version to the affected range: versions prior to 148.0.7778.168 are vulnerable
    Affected if Your installed version falls within the range below 148.0.7778.168

You are affected if Google Chrome is installed and its version number is less than 148.0.7778.168
