CVE-2024-29040 (GCVE-0-2024-29040)

Vulnerability from cvelistv5 – Published: 2024-06-28 21:02 – Updated: 2025-11-04 17:19
VLAI?
Summary
This repository hosts source code implementing the Trusted Computing Group's (TCG) TPM2 Software Stack (TSS). The JSON Quote Info returned by Fapi_Quote has to be deserialized by Fapi_VerifyQuote to the TPM Structure `TPMS_ATTEST`. For the field `TPM2_GENERATED magic` of this structure any number can be used in the JSON structure. The verifier can receive a state which does not represent the actual, possibly malicious state of the device under test. The malicious device might get access to data it shouldn't, or can use services it shouldn't be able to. This issue has been patched in version 4.1.0.

CVE-2024-29039 (GCVE-0-2024-29039)

Vulnerability from cvelistv5 – Published: 2024-06-28 15:48 – Updated: 2025-11-04 17:19
VLAI?
Summary
tpm2 is the source repository for the Trusted Platform Module (TPM2.0) tools. This vulnerability allows attackers to manipulate tpm2_checkquote outputs by altering the TPML_PCR_SELECTION in the PCR input file. As a result, digest values are incorrectly mapped to PCR slots and banks, providing a misleading picture of the TPM state. This issue has been patched in version 5.7.
Severity ?

CVE-2023-22745 (GCVE-0-2023-22745)

Vulnerability from cvelistv5 – Published: 2023-01-19 22:12 – Updated: 2025-11-21 19:10
VLAI?
Summary
tpm2-tss is an open source software implementation of the Trusted Computing Group (TCG) Trusted Platform Module (TPM) 2 Software Stack (TSS2). In versions prior to 4.1.0-rc0, 4.0.1, and 3.2.2-rc1, `Tss2_RC_SetHandler` and `Tss2_RC_Decode` both index into `layer_handler` with an 8 bit layer number, but the array only has `TPM2_ERROR_TSS2_RC_LAYER_COUNT` entries, so trying to add a handler for higher-numbered layers or decode a response code with such a layer number reads/writes past the end of the buffer. This Buffer overrun, could result in arbitrary code execution. An example attack would be a MiTM bus attack that returns 0xFFFFFFFF for the RC. Given the common use case of TPM modules an attacker must have local access to the target machine with local system privileges which allows access to the TPM system. Usually TPM access requires administrative privilege. Versions 4.1.0-rc0, 4.0.1, and 3.2.2-rc1 fix the issue.
