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).
