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 ANGLE in Google Chrome prior to 148.0.7778.216 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Critical)
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 in the ANGLE graphics library in Google Chrome versions prior to 148.0.7778.216 allows remote attackers to achieve arbitrary code execution through a maliciously crafted HTML page. The vulnerability involves improper memory management where memory is accessed after being freed, potentially enabling an attacker to control execution flow.

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 versionNavigate to chrome://settings/help or run 'google-chrome --version' (Linux) or look at 'About Google Chrome' in the menu (Windows/Mac)Affected if Version is below 148.0.7778.215
-
Confirm ANGLE library is in useInspect Chrome's internal components: go to chrome://gpu or look for libangle.dll (Windows), libangle.so (Linux), or libangle.dylib (Mac) in the Chrome installation directoryAffected if ANGLE library is present and being used for graphics rendering
-
Verify WebGL is enabledNavigate to chrome://settings and search for 'Hardware acceleration', or visit chrome://gpu to check WebGL status under the 'Graphics' sectionAffected if WebGL is enabled (this enables ANGLE for graphics rendering)
If Chrome version is below 148.0.7778.215 and ANGLE/WebGL is in use, the environment is affected by this use-after-free vulnerability.
