An issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) (Exynos chipsets) software. They allow attackers to conduct RPMB state-change attacks because an unauthorized RPMB write operation can be replayed, a related issue to CVE-2020-13799. The Samsung ID is SVE-2020-18100 (December 2020).
Weakness
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
