STATUS_RTPM_INVALID_CONTEXT
Invalid remote TPM context
STATUS_RTPM_INVALID_CONTEXT means the continuation state for a remote TPM operation cannot be trusted or decoded. Because the context carries operation state between steps, byte-level corruption or mixing contexts from different instances breaks the exchange.
The safe response is to restart the remote TPM operation. Attempting to repair a serialized context is risky because it can desynchronize authorization, PCR selection, command payload, or target identity.
Diagnostic focus
- Check for truncation, encoding changes, compression bugs, or storage corruption in the serialized context.
- Ensure the context is resumed against the same target and operation instance that created it.
- Restart the operation after invalid context rather than continuing with guessed state.
