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 · uneditedUse after free in Animation in Google Chrome prior to 138.0.7204.49 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)
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 · moderate confidenceA use-after-free vulnerability exists in Google Chrome's Animation component prior to version 138.0.7204.49. The vulnerability occurs when memory for an animation object is freed but a pointer to that memory remains active, leading to heap corruption when the dangling pointer is dereferenced. A remote attacker can trigger this via a specially crafted HTML page.

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 if Google Chrome is installedLocate the Chrome executable. On Windows, check C:\Program Files\Google\Chrome\Application\chrome.exe. On macOS, check /Applications/Google Chrome.app. On Linux, check /usr/bin/google-chrome or /opt/google/chrome/google-chrome.Affected if Google Chrome browser is present on the system
-
Determine the installed Chrome versionOpen chrome://settings/help in the Chrome browser, or run 'google-chrome --version' in terminal on Linux/macOS. On Windows, you can also right-click chrome.exe and view Properties > Details > File version.Affected if The displayed version number is lower than 138.0.7204.49 or the command returns a version older than 138.0.7204.49
-
Verify the Animation component is in useThis is a built-in Chrome component used for web animations. No user configuration is required. The vulnerability triggers when Chrome renders a specially crafted HTML page with specific animation sequences.Affected if Chrome is used to browse untrusted web content (the attack requires viewing a malicious HTML page)
The user is affected if Google Chrome is installed and its version is lower than 138.0.7204.49, and the browser has been used to view web content.
