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
Out of bounds write in Skia in Google Chrome prior to 146.0.7680.75 allowed a remote attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity: High)

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

Out-of-bounds write vulnerability in Skia (Google's 2D graphics library) within Google Chrome versions prior to 146.0.7680.75. A remote attacker can exploit this by tricking users into visiting a crafted HTML page, potentially allowing arbitrary code execution or denial of service via memory corruption.

MitigationUpdate Google Chrome to version 146.0.7680.75 or later. Organizations should deploy browser updates through their patch management infrastructure and verify complete coverage across managed endpoints.

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 Chrome version
    Navigate to chrome://settings/help or use 'Google Chrome' > 'About Google Chrome' in the menu to view the installed version number
    Affected if Version number is lower than 146.0.7680.80
  2. Verify Chrome is processing HTML content
    Confirm that the Chrome browser is being used to render or open HTML files or web pages
    Affected if The browser processes untrusted HTML content from web browsing or opened local HTML files

The environment is affected if the installed Google Chrome version is lower than 146.0.7680.80 and the browser processes HTML content from any source.
