Routine

MEDIUM 4.4MITIGATE

CVE-2022-25332 is a medium-severity flaw (CVSS 4.4) affecting omap l138 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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).
