AI Analysis

Impact

A use‑after‑free bug was discovered in the Device class of Google Chrome on macOS. The flaw occurs when a crafted HTML page is rendered, freeing a resource that is still referenced by the browser. An attacker can exploit the dangling pointer to execute arbitrary code outside the Chrome sandbox, enabling full system compromise. The weakness is a classic memory‑management flaw, classified as CWE‑416, and the Chromium team rated it high seriousness.

Affected Systems

Google Chrome on macOS users running a version older than 153.0.8010.36 are impacted. The vulnerability affects the browser engine that processes HTML content on Mac desktops.

Risk and Exploitability

The flaw carries a high severity rating, with a CVSS score of 9.6. EPSS is below 1%, and it is not listed in the CISA KEV catalog. The most likely attack vector is a remote web page that an authenticated or unauthenticated user can open. Because the vulnerability allows execution outside the sandbox, the threat surface includes full system compromise if the attack succeeds.
