TBSIMP_E_INVALID_OUTPUT_POINTER
Locate the first producer
TBSIMP_E_INVALID_OUTPUT_POINTER (0x80290207) belongs to the public and internal TPM Base Services path. It indicates an internal TBS call chain received no valid location in which to return a handle or result.
Data to retain
| Question | Evidence |
|---|---|
| What exact state was rejected? | an internal TBS call chain received no valid location in which to return a handle or result |
| Which layer owns the result? | The TBS client library, local RPC service and command scheduler before or around device execution. |
| What must be correlated? | public output arguments, RPC stub data, pointer and length pair, process bitness, application verifier evidence, and service event |
| Controlled comparison | use a minimal caller with stable writable output storage and compare 32-bit and 64-bit behavior only if relevant |
Verification sequence
The one-variable check is to use a minimal caller with stable writable output storage and compare 32-bit and 64-bit behavior only if relevant. Record the before/after state that the result command is allowed to change. If the operation can have side effects, use a disposable key, session, counter or NV index rather than production material.
- Capture this result and
0x80290207at the first code-specific return boundary. - Decode the result state: TBS function, context, pointer and buffer contract, service state, command size and nested status.
- Run the controlled comparison once and preserve both binary transcripts.
- Verify the expected output or state transition instead of relying on absence of a UI message.
Codes that answer different questions
| Comparison code | Built-in distinction |
|---|---|
TBSIMP_E_INVALID_PARAMETER | One or more parameters is invalid. |
TBSIMP_E_TPM_ERROR | An error occurred while communicating with the TPM. |
TBSIMP_E_RPC_INIT_FAILED | The RPC subsystem could not be initialized. |
It specifically answers whether an internal TBS call chain received no valid location in which to return a handle or result. In contrast, TBS_E_INVALID_OUTPUT_POINTER is the documented public result for this class.
Exit condition for the incident
To remediate it, repair caller memory ownership or service marshalling defects; changing TPM data cannot fix an output address. Do not restart or disable TBS before capturing its service and event data. Most caller-contract errors are reproducible without touching TPM ownership, firmware state or stored keys.
