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
Lack of special casing of Android ashmem in Google Chrome prior to 65.0.3325.146 allowed a remote attacker who had compromised the renderer process to bypass inter-process read only guarantees 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

Google Chrome prior to 65.0.3325.146 failed to properly handle Android ashmem (shared memory) regions, allowing a compromised renderer process to bypass inter-process read-only memory protections via a specially crafted HTML page.

MitigationUpdate Google Chrome to version 65.0.3325.146 or later to obtain the patch that properly handles Android ashmem memory protections.

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. Check installed Google Chrome version
    Open Chrome, go to Menu > Help > About Google Chrome, or navigate to chrome://settings/help. Alternatively, run 'google-chrome --version' or 'chromium-browser --version' in terminal.
    Affected if Version number is lower than 65.0.3325.146
  2. Verify Chrome is used on the system
    Check if Chrome/Chromium browser is installed by running 'which google-chrome' or 'which chromium-browser', or look for Chrome in application menus.
    Affected if Chrome is installed and the version from step 1 is < 65.0.3325.146
  3. Confirm ashmem-related feature availability
    This vulnerability targets the ashmem (Android Shared Memory) handling in Chrome's renderer process. The attack surface exists whenever Chrome's rendering engine processes web content.
    Affected if Chrome is used to browse untrusted web pages and version is vulnerable

A user is affected if Google Chrome (or Chromium) version lower than 65.0.3325.146 is installed and used to render web content, allowing a compromised renderer to potentially bypass inter-process memory protections via specially crafted HTML.
