Google just pushed out a fresh desktop build based on Chrome 156 that fixes 52 security vulnerabilities across Windows, Mac, and Linux. You will want to look out for version 156.0.8078.73 or .74 on Windows and Mac, while Linux users are getting .73 over the coming days.

This new patch comes barely a week after the initial Chrome 156 update was released with over 350 security fixes. That makes over 400 squashed bugs for the browser in roughly seven days, which is a massive run even by Chromium standards.

Out of the 52 flaws patched today, four are marked as critical. All four were reported by researcher Xinyang Ge at Anthropic, with two of them directly credited to assistance from the Claude AI model.

These critical bugs mostly involve memory corruption and use-after-free errors in how Chrome handles files, page layouts, and graphics. To keep things simple, what you need to know is that these are serious glitches that can make Chrome mishandle computer memory. In some cases, they could let someone crash your browser or run malicious code if you visit a compromised website.

We have been seeing a clear pattern with these patches lately, going back to early October when Chrome 155 fixed 247 security flaws with heavy involvement from AI tools. Alongside Anthropic’s huge haul in today’s release, OpenAI’s Codex Security team also flagged four high-severity memory bugs in the PDF viewer, video handler, and JavaScript engine.

As expected, Google is keeping the exact technical details of these flaws locked down for now, noting in its release blog that “access to bug details and links may be kept restricted until a majority of users are updated with a fix.” 

While desktop users get these critical security patches, Google has also been busy shipping Chrome M156 to Googlebook to finally stop 1Password crashes and broken keyboard shortcuts. Even smaller intermediate patches like the mid-October Chrome 155 update carried urgent memory fixes, so skipping these seemingly minor patches is a bad idea.

PiunikaWeb’s Take

This month’s patch surge shows AI bug hunting has transformed browser security. Claude and Codex are finding dozens of deep memory flaws weekly, exposing vulnerabilities hidden in Chromium for years.

The catch is that bad actors can use similar AI tools, so once a changelog goes public, they may quickly target anyone running an outdated build. To stay protected, you can install this patch now instead of waiting for Chrome to update in the background. Just click the three-dot menu in the top-right corner, go to Help, and select About Google Chrome to start the download and restart.

I cover fast-moving stories across apps, online platforms, and everyday tech — phones, wearables, consoles, and whatever else people are fighting with this week. Bugs, rollouts, scams, policy enforcement, and the occasional internet-culture rabbit hole are all fair game. My goal is simple — make confusing tech news readable. When I'm not working, I'm working out or chilling with my dog. Got a tip? You can find me on X @dcubbins.
