CVE-2022-25332

The AES implementation in the Texas Instruments OMAP L138 (secure variants), present in mask ROM, suffers from a timing side channel which can be exploited by an adversary with non-secure supervisor privileges by managing cache contents and collecting timing information for different ciphertext inputs. Using this side channel, the SK_LOAD secure kernel routine can be used to recover the Customer Encryption Key (CEK).

CWE-203 Observable Discrepancy

The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not.

CWE-208 Observable Timing Discrepancy

Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not.
