Local information disclosure via predictable AES-GCM output
Published Jan 7, 2020 · Updated Aug 4, 2024
Information disclosure in Android 10 Titan M cryptographic operations allows local users to expose data without user interaction. Titan M-backed StrongBox AES-GCM operations can return a repeated 0dd0adde ciphertext pattern after a roughly two-second delay instead of randomized output, without raising an exception. Exploitation requires local code to request StrongBox-backed AES-GCM operations; no integrity or availability impact is reported.
