These vulnerabilities stem from issues like type Confusion in the V8 engine and race conditions. Inappropriate implementation across components such as DevTools, Downloads, Google Updater, WebRTC and Split View. Moreover, these vulnerabilities come from the use-after-free bugs in Media Stream and Digital Credentials and bad cast issues in Loader.
Simply put, these bugs could let a malicious website run harmful code on your system without you realising it.
Which versions are affected?
For Google Chrome:
- Versions before 143.0.7499.40/41 on Windows and macOS
- Versions before 143.0.7499.40 on Linux
For Microsoft Edge, Stable Channel before 143.0.3650.66 are affected. Anyone running older versions is at risk, and CERT-In has advised organisations and individual users to update immediately.
The concern is that exploiting these flaws doesn’t require much interaction. You simply have to open a malicious webpage or click an unsafe link. Once you open a malicious link, it can lead to a successful attack, which means:
- Remote code execution
- Access to personal or financial data
- Privilege escalation
- Browser or system crashes
- Spoofing attacks and security bypass
What Should You Do?
In such cases, updating is one of the important factors that can save you, and it is pretty simple, which takes less than a minute.
- For Chrome, open Chrome
- Go to Menu, then Help, and click on the About Google Chrome
- Chrome will automatically check for updates and install the latest version
For Edge users:
- Open Microsoft Edge
- Then go to Menu, and then Help & Feedback.
