Google has issued a patch for a high‑severity Chrome zero‑day, tracked as CVE‑2026‑2441, a memory bug in how the browser handles certain font features that attackers are already exploiting.
CVE-2026-2441 has the questionable honor of being the first Chrome zero-day of 2026. Google considered it serious enough to issue a separate update of the stable channel for it, rather than wait for the next major release.
How to update Chrome
The latest version number is 145.0.7632.75/76 for Windows and macOS, and 145.0.7632.75 for Linux. So, if your Chrome is on version 145.0.7632.75 or later, it’s protected from these vulnerabilities.
The easiest way to update is to allow Chrome to update automatically. But you can end up lagging behind if you never close your browser or if something goes wrong, such as an extension preventing the update.
To update manually, click the More menu (three dots), then go to Settings > About Chrome. If an update is available, Chrome will start downloading it. Restart Chrome to complete the update, and you’ll be protected against these vulnerabilities.
Google confirms it has seen active exploitation but is not sharing who is being targeted, how often, or detailed indicators yet.
But we can derive some information from what we know.
The vulnerability is a use‑after‑free issue in Chrome’s CSS font feature handling (CSSFontFeatureValuesMap), which is part of how websites display and style text. More specifically: The root cause is an iterator invalidation bug. Chrome would loop over a set of font feature values while also changing that set, leaving the loop pointing at stale data until an attacker managed to turn that into code execution.
Use-after-free (UAF) is a type of software vulnerability where a program attempts to access a memory location after it has been freed. That can lead to crashes or, in some cases, lets an attacker run their own code.
The CVE-record says, “Use after free in CSS in Google Chrome prior to 145.0.7632.75 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page.” (Chromium security severity: High)
This means an attacker would be able to create a special website, or other HTML content that would run code inside the Chrome browser’s sandbox.
Chrome’s sandbox is like a secure box around each website tab. Even if something inside the tab goes rogue, it should be confined and not able to tamper with the rest of your system. It limits what website code can touch in terms of files, devices, and other apps, so a browser bug ideally only gives an attacker a foothold in that restricted environment, not full control of the machine.
Running arbitrary code inside the sandbox is still dangerous because the attacker effectively “becomes” that browser tab. They can see and modify anything the tab can access. Even without escaping to the operating system, this is enough to steal accounts, plant backdoors in cloud services, or reroute sensitive traffic.
If chained with a vulnerability that allows a process to escape the sandbox, an attacker can move laterally, install malware, or encrypt files, as with any other full system compromise.
How to stay safe
To protect your device against attacks exploiting this vulnerability, you’re strongly advised to update as soon as possible. Here are some more tips to avoid becoming a victim, even before a zero-day is patched:
Don’t click on unsolicited links in emails, messages, unknown websites, or on social media.
Enable automatic updates and restart regularly. Many users leave browsers open for days, which delays protection even if the update is downloaded in the background.
Use an up-to-date, real-time anti-malware solution which includes a web protection component.
Users of other Chromium-based browsers can expect to see a similar update.

Cybersecurity risks should never spread beyond a headline. Protect your, and your family’s, personal information by using identity protection.
There’s an entire surveillance network popping up across the United States that has likely already captured your information, all for the non-suspicion of driving a car.
Automated License Plate Readers, or ALPRs, are AI-powered cameras that scan and store an image of every single vehicle that passes their view. They are mounted onto street lights, installed under bridges, disguised in water barrels, and affixed onto telephone poles, lampposts, parking signs, and even cop cars.
Once installed, these cameras capture a vehicle’s license plate number, along with its make, model, and color, and any identifying features, like a bumper sticker, or damage, or even sport trim options. Because nearly every ALPR camera has an associated location, these devices can reveal where a car was headed, and at what time, and by linking data from multiple ALPRs, it’s easy to determine a car’s daylong route and, by proxy, it’s owner’s daily routine.
This deeply sensitive information has been exposed in recent history.
But there’s another concern with ALPRs besides data security and potential vulnerability exploits, and that’s with what they store and how they’re accessed.
ALPRs are almost uniformly purchased and used by law enforcement. These devices have been used to help solve crime, but their databases can be accessed by police who do not live in your city, or county, or even state, and who do not need a warrant before making a search.
In fact, when police access the databases managed by one major ALPR manufacturer, named Flock, one of the few guardrails those police encounter is needing to type a single word in a basic text box. When Electronic Frontier Foundation analyzed 12 million searches made by police in Flock’s systems, they learned that police sometimes filled that text box with the word “protest,” meaning that police were potentially investigating activity that is protected by the First Amendment.
Today, on the Lock and Code podcast with host David Ruiz, we speak with Will Freeman, founder of the ALRP-tracking project DeFlock Me, about this growing tide of neighborhood surveillance and the flimsy protections afforded to everyday people.
“License plate readers are a hundred percent used to circumvent the Fourth Amendment because [police] don’t have to see a judge. They don’t have to find probable cause. According to the policies of most police departments, they don’t even have to have reasonable suspicion.”
