Last modified

CVE-2022-25332 is a medium-severity vulnerability rated 4.1/10 on the CVSS scale. 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).. EPSS estimates a 0.10% chance of exploitation in the next 30 days.
