Google Project Zero revealed 18 vulnerabilities in Exynos modems in late 2022 and early 2023. Notably, four of the flaws including CVE-2023-24033, involve internet-to-baseband remote code execution.

According to information via 9to5Google, this vulnerability requires certain 5G features to be turned on, so completely disabling those features may protect your device. If those 5G features are not operational, there will be no fear of being vulnerable.

As long as Wi-Fi Calling is off and VoLTE is disabled, your Samsung and Google devices should be more secure from the Exynos flaw. We can expect Google will soon release security patches to fix the issue.

How to disable Wi-Fi calling and VoLTE?

You can easily turn off the Wi-Fi calling feature on your Samsung Galaxy S22 smartphone, just need to follow the steps mentioned below.

• Open Settings on your Galaxy devices.
• Click on the Connections.

• Now, tap on the Wi-Fi Calling option.

• If the feature is enabled then you can turn it off by tapping on the toggle.

To disable the VoLTE function, you have to visit the Mobile networks option under the Connections tab. Look for VoLTE calls and turn the function off.

On Google Pixel 6 series smartphones, you can turn off Wi-Fi calling feature through Settings >> Network & internet >> Calls & SMS >> Wi-Fi calling >> turn it off. Make sure to disable this functionality for each SIM.

VoLTE can’t be disabled on Google Pixel 6 as it looks like a software update in 2021 automatically enabled VoLTE and removed the toggle.
