How to check if your Google Chrome browser is secure

  1. Go to Settings.
  2. Click on Help.
  3. Go to About Google Chrome.
  4. Google Chrome versions 94.0.4606.61 or higher are protected.
  5. If you don’t have this version, you can’t do anything, wait, or you can shut down the machine.

Google states that the new 94.0.4606.54 will rollout over the coming days/weeks, and so you might not be able to protect yourself right now.

The company has revealed five threats that are under ‘Use-After-Free’ vulnerabilities. Use After Free or UAF is a popular error of not clearing the memory after it is free. It leads a program to crash, and hackers can use this to attack your Chrome. The higher security risks are:
