CVE-2022-28793

Root-of-trust alteration via mutable StrongBox state

Published May 3, 2022 · Updated Aug 3, 2024

Improper state maintenance in StrongBox on Samsung Mobile Devices before Galaxy S22 allows local users to alter the Android root of trust. StrongBox fails to lock the Android root-of-trust state after its first boot initialization, permitting later changes during the device boot cycle. Exploitation requires prior compromise and control of the trusted execution environment, and the bounded consequence is loss of Android root-of-trust integrity.
