Samsung's security vulnerabilities addressed include issues related to manual package installation via ADB command, improper audio system access control, UWB chipset identifier, broadcast SMS configuration, and Galaxy Themes Service, among others. Settings suffered from improper access control problems, and certain internal testing functions experienced out-of-bounds write issues, which could potentially allow unauthorized code execution.

Most detected vulnerabilities are found in devices running Android 11, Android 12, Android 12L, and Android 13. Some issues are specifically related to Qualcomm chips and components, Mali and PowerVR GPUs, and memory management.

Owners of the Galaxy S21 series residing in the aforementioned countries can download the new update. Introduced by Samsung in early 2021 with Android 11 pre-installed, the Galaxy S21 series later received the Android 12 update in late 2021 and the Android 13 update in late 2022. Samsung is expected to release the Android 14-based One UI 6.0 update for the Galaxy S21 series later this year.
