On certain Samsung P(9.0) phones, an attacker with physical access can start a TCP Dump capture without the user's knowledge. This feature of the Service Mode application is available after entering the *#9900# check code, but is protected by an OTP password. However, this password is created locally and (due to mishandling of cryptography) can be obtained easily by reversing the password creation logic.

An issue was discovered on Samsung mobile devices with N(7.0), O(8.0) (exynos7420 or Exynos 8890/8996 chipsets) software. Cache attacks can occur against the Keymaster AES-GCM implementation because T-Tables are used; the Cryptography Extension (CE) is not used. The Samsung ID is SVE-2018-12761 (September 2018).

In RELIC before 2020-08-01, RSA PKCS#1 v1.5 signature forgery can occur because certain checks of the padding (and of the first two bytes) are inadequate. NOTE: this requires that a low public exponent (such as 3) is being used. The product, by default, does not generate RSA keys with such a low number.
