Google has released a significant security update for Chrome, patching 12 vulnerabilities that could enable browser-based attacks on UK businesses.
The update brings Chrome to version 150.0.7871.181/.182 for Windows and Mac, and 150.0.7871.181 for Linux
, addressing multiple high-risk memory corruption flaws that attackers could exploit simply by tricking staff into visiting a malicious webpage.
For Kent SMEs running Chrome across their offices—which is most businesses given Chrome’s dominance—this update requires immediate attention. The vulnerabilities affect core Chrome components, and
nine of the twelve bugs are rated “High” severity
, meaning they present serious security risks if left unpatched.
What Vulnerabilities Does This Chrome Security Update Fix?
The update addresses flaws across multiple Chrome components, including V8, ANGLE, Skia, GPU, UI, Extensions, and Chromecast
. These technical components handle everything from JavaScript execution to graphics rendering—essential functions that run every time your staff open a webpage.
Vulnerabilities involving type confusion, use-after-free, and buffer overflows are particularly dangerous because they affect how Chrome manages memory
. The practical risk?
If exploited, attackers could potentially execute malicious code, crash the browser, or gain unauthorised access to system resources simply by getting a victim to visit a compromised or malicious webpage
.
Two vulnerabilities in this update were discovered by AI-powered security research systems, highlighting how artificial intelligence is driving record vulnerability discovery volumes across the technology sector.
High-Risk Memory Corruption Flaws
The V8 stack buffer overflow (CVE-2026-16418) and GPU/UI use-after-free bugs (CVE-2026-16423, CVE-2026-16424) stand out as high-risk since they touch core browser functions
. V8 is Chrome’s JavaScript engine—the component that runs interactive elements on virtually every modern website. When this component has vulnerabilities, every webpage your staff visit becomes a potential attack vector.
Why This Matters for UK SMEs Running Chrome
Chrome remains the most widely used browser in UK businesses. According to recent UK Government research,
43% of businesses experienced a cyber security breach or attack during the previous 12 months, with the figure increasing to 65% for medium-sized businesses and 69% for large businesses
.
Browser vulnerabilities represent a particularly insidious threat because:
- Staff use browsers constantly throughout the working day
- Exploits can be delivered through legitimate-looking websites
- No special user action is required beyond visiting a webpage
- Attacks can bypass traditional antivirus solutions
- Compromised browsers can access business email, cloud applications, and customer data
Enterprises managing Chrome deployments across multiple endpoints should prioritise pushing this update through their device management systems, given the presence of multiple High-severity memory corruption bugs that could be chained together in sophisticated attacks
.
How to Update Chrome in Your UK Business
The good news is that updating Chrome is straightforward, but it requires active management to ensure all business devices are protected.
For Individual Workstations
Chrome typically updates automatically, but the update only completes when users restart their browser. Many staff leave Chrome running for days or weeks, which means they’re using outdated, vulnerable versions without realising it.
To check and apply the update manually:
- Click the three-dot menu in the top-right corner of Chrome
- Select ‘Help’ then ‘About Google Chrome’
- Chrome will check for and download any available updates
- Click ‘Relaunch’ to complete the installation
- Verify you’re running version 150.0.7871.181 or later
For Managed Business Environments
If your business uses centralised device management (such as Microsoft Intune, Group Policy, or third-party tools), you should:
- Verify your Chrome update policies are configured and active
- Check deployment logs to confirm the update is rolling out
- Identify any devices that haven’t updated within 48 hours
- Force a browser restart policy if necessary to complete the update
This update comes just days after Firefox released emergency patches for two zero-day vulnerabilities, highlighting the current intensity of browser security challenges facing UK businesses.
Chrome Security in the Context of July 2026’s Patch Landscape
This Chrome update represents the latest in an unprecedented volume of security patches released in July 2026. UK SMEs are facing what one security researcher described as a “whopping” increase in vulnerability disclosures, driven largely by AI-assisted security research finding flaws faster than ever before.
Earlier this month, Microsoft released patches for 569 vulnerabilities in a single Patch Tuesday, whilst Adobe moved to a twice-monthly patching schedule to manage the increased volume of security fixes.
For Kent SMEs, this escalation creates a genuine challenge: how do you keep up with security updates when they’re being released at record volumes across multiple vendors?
Five Practical Steps for Managing Browser Security
Beyond simply installing this week’s Chrome update, UK SMEs should implement systematic browser security management:
1. Enable Automatic Updates and Verify They’re Working
Don’t assume automatic updates are functioning. Check a sample of workstations monthly to confirm they’re running current browser versions. Staff who never close their browsers won’t receive updates even if auto-update is enabled.
2. Implement a Browser Restart Policy
Consider a policy requiring staff to restart browsers at least weekly, or use device management tools to enforce automatic browser restarts during off-hours. This ensures updates actually complete.
3. Maintain an Inventory of Browser Extensions
This update patches vulnerabilities in Chrome’s Extensions component. Review which extensions your staff have installed, remove any that aren’t business-essential, and maintain an approved list of vetted extensions.
4. Monitor Security Advisories
Subscribe to Google’s Chrome Releases blog and security mailing lists. For businesses without dedicated IT staff, partnering with a local IT support provider ensures you don’t miss critical security updates.
5. Test Browser-Based Business Applications
After major browser updates, quickly test your critical web applications—accounting software, CRM systems, cloud storage—to identify any compatibility issues before they disrupt operations.
Don’t Navigate Chrome Security Updates Alone
Managing browser security updates across your business shouldn’t fall to already-stretched office managers or become another task competing for your attention as a business owner. With
the National Cyber Security Centre reporting it handled 204 nationally significant cyber attacks in the year to August 2025, an average of four each week and more than twice the 89 recorded in the previous year
, keeping browsers patched is no longer optional—it’s essential business protection.
