Google Chrome Patches 382 Flaws at Once, With AI Driving the Record
Google recently released Chrome 151, an exceptional security update: 382 vulnerabilities were patched in this single release, including 15 deemed critical. Nearly all of these flaws were uncovered internally by Google, most likely with the help of AI. Here’s what we know about these vulnerabilities.
382 flaws, including 15 critical ones
The number is striking, at least for now. Where a Chrome update usually fixes only a few dozen issues, the stable version released on Tuesday, June 30, 2026, patches 382 at once. That volume could soon become the norm, since Google is using AI to identify flaws in its web browser.
According to the security bulletin published by Google, Chrome 151 is being rolled out gradually on Windows, macOS, and Linux. The same bulletin lists 382 fixes, broken down as follows:
- 15 critical flaws,
- 67 high-severity flaws,
- 169 medium-severity flaws,
- 131 low-severity flaws.
There is a wide variety of vulnerability types discovered (use-after-free, out-of-bounds, type confusion, uninitialized use). What matters most is that the vast majority of these vulnerabilities can be triggered using a booby-trapped web page. Still, there is good news: there is no active exploitation of these 382 flaws, so there are no zero-days.
AI in the background: Google found 358 of the 382 flaws
358 of the 382 vulnerabilities were discovered by Google. In the past, it was rare for Google to find so many issues in-house, just as it was rare to see so many flaws fixed in a single update. This is explained by the use of AI, as other vendors do, including the Mozilla Foundation for the Firefox browser.
This trend has been documented by VulnCheck, and I mentioned it in an article discussing this true tsunami of security flaws in 2026, with a +563% increase for Chrome. The current pace confirms this trend. Just a few weeks ago, Google had already patched 74 vulnerabilities, including a zero-day flaw that was actively exploited. And before that, Chrome 148 was already described as a "historic" release with 127 fixes. Suffice it to say, the limits keep being pushed every time...
That said, Google still makes sure to reward the researchers who discover flaws through its bug bounty program. For example, Google paid out $36,000 for a single flaw (CVE-2026-13789, a use-after-free in the GPU component), a sign that securing Google Chrome also depends on the work of external researchers.
All that’s left now is to update Google Chrome on your machine! The versions to install are:
- Linux: Chrome 150.0.7871.46
- Windows/Mac: 150.0.7871.46/.47
