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
Heap buffer overflow in UI in Google Chrome on Android prior to 86.0.4240.185 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape 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

Heap buffer overflow vulnerability in the UI component of Google Chrome on Android prior to version 86.0.4240.185. A remote attacker with an already compromised renderer process could exploit this via a crafted HTML page to potentially escape the sandbox and execute arbitrary code.

MitigationUpdate Google Chrome for Android to version 86.0.4240.185 or later. Organizations should leverage mobile device management (MDM) to enforce Chrome updates or verify compliance across managed devices.

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. Identify if Google Chrome for Android is installed
    Check the list of installed applications on the Android device. Navigate to Settings > Apps and look for Google Chrome in the app list.
    Affected if Google Chrome for Android is present on the device
  2. Determine the installed version of Google Chrome
    Open Google Chrome, tap the three-dot menu, go to Settings > About Chrome. The version number is displayed on this page.
    Affected if The displayed version number is less than 86.0.4240.185 (for example, 86.0.4240.111 or earlier)
  3. Verify the attack surface exists
    Confirm that Chrome is used as the default browser or that users access untrusted web content. This vulnerability is in the UI component and is triggered when the renderer process has already been compromised.
    Affected if Chrome processes untrusted web content and the device runs an affected version

A device is affected if Google Chrome for Android is installed with a version number lower than 86.0.4240.185 and the device accesses web content, since exploitation requires a compromised renderer process which can be triggered through crafted HTML pages.
