Google abruptly issued an urgent Chrome update, alerting users to the fact that assaults had exploited a flaw that its Threat Analysis Group found. Because of how serious the risk is, Google also acknowledged that the problem “was mitigated on 2025-05-28 by a configuration change” that was pushed out to all platforms prior to this update.
All information on the vulnerability will “be kept restricted until a majority of users are updated with a fix,” according to Google, which also states that it “is aware that an exploit for CVE-2025-5419 exists in the wild.” If the flaw is present in a third-party library that other projects rely on in a similar way but haven’t yet resolved, we will also keep the restrictions in place.
The world’s most popular browser usually fixes memory flaws like CVE-2025-5419, which is an out of bounds read and write in V8. Even though it is merely classified as high-severity, the fact that assaults are occurring makes the patch imperative.
Following a separate assault warning, the U.S. government has already ordered federal employees to update Chrome by Thursday or cease using the browser. Since then, two high-severity fixes have been included in another release. This most recent upgrade and warning will undoubtedly lead CISA to implement a 21-day update obligation as well.
This emergency release includes a second patch for CVE-2025-5068, a memory problem that was discovered by an outside researcher and is known as a “use after free in Blink.”
While CVE-2025-5419 applies to Chromium, NIST cautions that it “allows a remote attacker to potentially exploit heap corruption via a crafted HTML page,” implying that other browsers will also receive emergency patches.
As per normal, your browser ought to display a notification indicating that the update has been downloaded. To make sure it works completely, you must restart Chrome. Unless you choose not to, all of your regular tabs will reopen after that. However, since your Incognito tabs won’t reopen, be sure to save any work or bookmark any URLs you wish to view later.
