STATUS_TPM_BAD_ATTRIBUTES
STATUS_TPM_BAD_ATTRIBUTES is a Windows NTSTATUS value in the TPM facility. For STATUS_TPM_BAD_ATTRIBUTES, it belongs to the TPM 1.2 error family and is normally surfaced through the Windows TPM stack, such as TPM Base Services, rather than by ordinary file, registry or network APIs.
TPM NV indexes are defined with attribute combinations for read, write, owner authorization, index authorization, locality and lock behavior. This status means the supplied attributes are not a valid combination.
This is usually found during NV definition or redefinition, not during ordinary reads. The fix is to correct the provisioning profile rather than to increase buffer size or retry with the same parameters.
Diagnostic focus
- Log the full NV attribute mask and the index size at definition time.
- Check for mutually incompatible read/write and authorization attributes.
- Review platform-specific reserved indexes before defining custom NV areas.
