Major Security Flaw Affects Google, Samsung Phones

Google has discovered and disclosed a set of severe security vulnerabilities in the Samsung modems found in many recent Google Pixel phones and some recent Samsung phones, mostly A-series models. Software updates made available this month fix the issue, but are not yet available for all models. The flaws allow an attacker to remotely compromise a phone with no user action, knowing only the victim's phone number. Users of the Google Pixel 6 series should immediately disable Wi-Fi Calling and VoLTE until a software update is available for those models. A software update has been released to address the issue on the Pixel 7 series. Also affected are the Samsung Galaxy A71, A53, A33, A21, A13, A12, and A04 series.
