ACM Errata
AS1. TXT.ERRORCODE TPM Command Return Code And Launch Control
Policy List Index And Minor Code Are Not Reported Correctly.
Problem: On affected SINIT ACM releases, the TXT.ERRORCODE register TPM command return
code (bits 24:16), Launch Control Policy List Index (bits 24:22) and Launch Control
Policy Minor Code (bits 21:16) are not reported correctly.
Implication: Software depending upon TXT.ERRORCODE error reporting for the TPM command
return code, Launch Control Policy List Index, or Launch Control Policy Minor Code may
not behave as expected.
Workaround: None.
Status: See Intel

for affected releases.
AS2. SINIT Buffer Overflow Vulnerability
Problem: SINIT Authenticated Code Module (ACM) 1.0 is susceptible to a buffer overflow issue.
Implication: When Intel® Trusted Execution Technology measured launch is invoked using SINIT
Authenticated Code Module 1.0, the platform is susceptible to an OS kernel-level
exploit which may compromise certain SINIT ACM functionality.
Workaround: It is possible for a BIOS update and an updated SINIT ACM 1.1 to be used as a
workaround for this erratum. Previous SINIT ACM releases will no longer function with
the BIOS update.
Status: See Intel
