Detailsinfo

A vulnerability was found in Texas Instruments OMAP L138 (the affected version unknown) and classified as problematic. Affected by this issue is the function SK_LOAD. The manipulation with an unknown input leads to a behavioral discrepancy vulnerability. Using CWE to declare the problem leads to CWE-205. The product's behaviors indicate important differences that may be observed by unauthorized actors in a way that reveals (1) its internal state or decision process, or (2) differences from other products with equivalent functionality. Impacted is confidentiality. CVE summarizes:

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).

The weakness was shared 10/19/2023. This vulnerability is handled as CVE-2022-25332 since 02/18/2022. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1592.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
