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.

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 confidenceInsufficient input validation in Chrome's WebGL implementation allows a remote attacker to read out-of-bounds memory by tricking users into visiting a crafted HTML page, potentially exposing sensitive memory contents.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed Chrome versionOpen Chrome, go to Menu > Help > About Google Chrome, or navigate to chrome://version/ in the address bar to see the full version numberAffected if Version number is less than 72.0.3626.81
-
Verify WebGL is enabledNavigate to chrome://flags/ in the browser and search for 'WebGL', or go to chrome://gpu/ and check the WebGL status under the Graphics sectionAffected if WebGL is listed as enabled or available (the vulnerability requires WebGL to be accessible)
-
Check Chrome package on Linux systemsOn Debian-based systems run: dpkg -l | grep chrome or apt list --installed | grep -i chrome. On RHEL/Fedora run: rpm -qa | grep -i chromeAffected if The installed Chrome package version is lower than 72.0.3626.81, or the distribution ships an unpatched Chrome version corresponding to Chrome < 72.0.3626.81
-
Confirm browser is used to visit untrusted web contentDetermine if the Chrome browser is used for general web browsing where untrusted HTML pages could be loadedAffected if Users can be tricked into visiting crafted HTML pages (this is the attack vector that triggers the vulnerability)
The environment is affected if Google Chrome version is below 72.0.3626.81 AND WebGL is enabled, allowing a remote attacker to read out-of-bounds memory through a malicious webpage.
