Version Google Chrome 133 of the popular web browser Chrome has been officially released, bringing with it a wide variety of improvements and more importantly, security fixes. This update makes patching Google Chrome Vulnerabilities a priority, as almost a dozen fixes have been added. Rolling out now, updates are expected to continue to come over the week, as version 133.0.6943.53 for Linux and 133.0.6943.53/54 for Windows and Windows have been made available. Users are strongly urged to execute the update for their browsers immediately, protecting their systems against these newly discovered vulnerabilities.
Google Chrome Vulnerabilities
The Google Chrome 133 update is particularly noteworthy because it addresses two high-severity use-after-free bugs, one in Skia (Chrome’s rendering engine) and the other in V8 (the JavaScript Engine used by Chrome). What makes these two stand out is the fact that the Google Chrome Vulnerabilities allowed attackers to potentially, remotely execute arbitrary code on a given system.
The first fix, marked as CVE-2025-0444, was the vulnerability found in Skia, the graphics library used by Chrome for image rendering and also for its many visual elements. A use-after-free vulnerability occurs when a program attempts to access memory that has been freed, which leads to unpredictable behavior and security risks, allowing for an exploit where memory could be manipulated and malicious code could be injected. The flaw was reported by Francisco Alonso (@revskills) on the 19th of January, 2025, earning a gracious reward of $7000 through Google Chrome vulnerability program.

The second high-severity risk, CVE-2025-0445, was found to reside within the V8 JavaScript engine. With the crucial role that V8 plays in processing JavaScript, even the most basic of exploits could have had devastating results. Thankfully, this flaw was noticed and reported by an anonymous researcher (user: 303f06e3), on the 27th of January, 2025. Since the user remains anonymous, the bounty for the vulnerability is yet to be revealed.
Last but not least, a medium-severity vulnerability, CVE-2025-0451, was discovered in the Extensions API. Categorized as an “inappropriate implementation,” this particular flaw was reported all the way back on the 18th of September, 2022, by Vitor Torres and Alesandro Ortiz. Although categorized as medium, this weakness in the Extensions API could be exploited by malicious extensions, therefore it being finally addressed is good news for all. A reward of $2000 was provided for the detection of this flaw.
Chrome Security Measures
Google Chrome 133 has taken the initiative to restrict detailed information on the bugs until a majority of the users have executed the update. This ensures that attackers cannot exploit any of the Google Chrome Vulnerabilities before the users are protected. Additionally, Google has also implemented various fixes from internal audits and fuzzing initiatives.


Given the major severity of the situation, users are strongly encouraged to immediately update their web browsers. In order to update Chrome, users can follow the steps provided here:
- Open Google Chrome.
- Click on the three-dot menu in the top right corner of the application.
- Navigate over to “Help”, then select “About Google Chrome”.
- The browser should then automatically check for and install the update if available.
- Relaunch Chrome to finalize the process.
Following these steps will ensure that your system and browser stay protected from any and all threats. Proactive measures such as these show that the team behind Chrome is truly committed to providing a safer browsing experience, and internal audits plus external research collaborations only further the fact. In this day and age, one must be well informed on such matters, and updates such as these take prime priority.
