CVE-2025-13633
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 Digital Credentials in Google Chrome prior to 143.0.7499.41 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption 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 confidenceA use-after-free vulnerability exists in the Digital Credentials component of Google Chrome versions prior to 143.0.7499.41. An attacker who has already compromised the renderer process can trigger this flaw via a crafted HTML page, potentially leading to heap corruption. This is a memory safety issue where the program continues to use a pointer after the memory it references has been freed.

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.
-
Determine installed Chrome versionOpen Chrome and navigate to chrome://version, or click Chrome menu > Help > About Google Chrome. Record the full version number shown.Affected if The installed version is less than 143.0.7499.40 (for example, 143.0.7499.39 or earlier)
-
Check Digital Credentials feature statusIn the Chrome address bar, go to chrome://flags and search for Digital Credentials or Web Authentication related flags. Note which features are enabled.Affected if Digital Credentials or related Web Authentication features are enabled on a vulnerable Chrome version
-
Verify renderer process integrityOpen Windows Task Manager or macOS Activity Monitor while Chrome is running. Look for multiple chrome.exe (Windows) or Google Chrome (Mac) processes in the list.Affected if Unusual数量的渲染器进程存在，或进程出现异常终止行为，且Chrome版本存在漏洞
如果Chrome版本低于143.0.7499.40且启用了相关功能，则存在受此CVE影响的风险。
