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 · uneditedOut of bounds write in JavaScript in Google Chrome prior to 79.0.3945.79 allowed a remote attacker to execute arbitrary code inside a sandbox 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 confidenceOut-of-bounds write vulnerability in Google Chrome's JavaScript engine (V8) prior to version 79.0.3945.79. A remote attacker can exploit this via a crafted HTML page to execute arbitrary code. While the vulnerability allows code execution, it is constrained by Chrome's sandbox, reducing but not eliminating the risk.

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 Google Chrome browser versionOpen Chrome, click the three-dot menu, select Help > About Google Chrome. The version number is displayed on that page. Alternatively, navigate to chrome://settings/help in the address bar.Affected if The displayed version is earlier than 79.0.3945.79 (for example, 78.0.3904.108, 78.5.0, etc.)
-
Check Chrome version on Debian LinuxRun command: dpkg -l | grep google-chrome or apt-cache policy google-chrome-stableAffected if The installed version shown is earlier than 79.0.3945.79, or the package is not installed but the system is Debian 9.0 or 10.0 with Chrome added from third-party repositories
-
Check Chrome version on FedoraRun command: rpm -qa | grep google-chrome or dnf list installed google-chrome-stableAffected if The installed version shown is earlier than 79.0.3945.79, or the system is Fedora 30 or 31 with Chrome installed from third-party repos
-
Check Chrome version on RHEL-based systemsRun command: rpm -qa | grep google-chrome or yum list installed google-chrome-stableAffected if The installed version shown is earlier than 79.0.3945.79, or the system is RHEL 6.0 (Desktop, Server, Workstation, or Scientific Computing) with Chrome installed
