Versal™ Adaptive SoC – Improper Configuration of the Secure Stream Switch during Post-Boot Cryptographic Operations
AMD ID: AMD-SB-8011
Potential Impact: N/A
Severity: N/A
Summary
In Versal™ Adaptive SoC devices, the Platform Loader and Manager (PLM) implements runtime (post-boot) software services that allows a remote processor to command the PLM to execute cryptographic operations – including AES, SHA3, RSA, ECDSA – on behalf of the remote processor. These operations require the Secure Stream Switch (SSS) to be configured such that the Direct Memory Access (DMA) hardware can send data to and read from these cryptographic engines.
A potential vulnerability exists with the configuration of the SSS because the PLM does not clear the SSS configuration after a cryptographic operation completes. This allows an improper SSS configuration when setting up the SSS for any following cryptographic command.
