CVE-2022-0609

CVE-2022-0609 is a use-after-free vulnerability (CWE-416) in the Animation component of Google's Chromium browser engine that can corrupt heap memory. A remote attacker triggers it by persuading a user to load a crafted HTML page (for example via a malicious or compromised website), with no authentication required beyond opening the page. Successful exploitation can lead to heap corruption and potentially arbitrary code execution in the context of the affected browser. Any browser or application built on Chromium is potentially affected, including Google Chrome, Microsoft Edge, and Opera. The flaw is actively exploited: CISA added it to the KEV catalog on 2022-02-15 with a required action to apply vendor updates, Google confirmed in-the-wild exploitation at disclosure, no public PoC is known, ransomware use is unknown, and EPSS assigns a 22.3% probability of exploitation within 30 days (98th percentile).

What to do: Apply the vendor updates immediately: Google fixed this in Chrome 98.0.4758.102 (February 2022), so update Chrome, Microsoft Edge, Opera, and any other Chromium-based browsers or Chromium-embedded applications to releases containing that Chromium fix, and inventory browser versions across your fleet to catch machines lagging on the update. Until fully patched, treat unsolicited links to web pages as an exploitation vector given confirmed in-the-wild use, and comply with CISA's KEV required action to apply updates per vendor instructions.
