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 · unedited
Use after free in Aura in Google Chrome on Windows prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape 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 confidence

Use-after-free vulnerability in Chrome's Aura UI framework on Windows (versions prior to 149.0.7827.103). A remote attacker with an already-compromised renderer process can exploit this via crafted HTML to potentially escape the sandbox and execute code outside the browser's security context.

MitigationUpgrade Google Chrome to version 149.0.7827.103 or later on all Windows systems. This is a browser patch; no application code changes are required unless the client is building a Chromium-based browser.
