Samsung has already patched the security vulnerability in Qualcomm models on some devices
A few days ago Check Point Research revealed a vulnerability in Qualcomm modems that could allow attackers to listen to your calls, read your texts, and more. Today, Samsung announced that they are aware of the vulnerability and that they have already patched a number of its devices.
Samsung has been rolling out patches for some of its Qualcomm-powered Galaxy devices since January (but the company does not specify which ones). Most other Galaxy devices will be secure when you install the patch on May 1, 2021.
The vulnerability in question is known as CVE-2020-11292. It is not mentioned in AOSP’s Android Security Bulletin to May, but it’s part of Samsung Security Update to May (with an asterisk for the units that got it earlier).
