Intel TDX MigTD: Information disclosure after improper cleanup in SPDM responder
Summary
An improper cleanup after a thrown exception in the SPDM responder of Intel TDX MigTD may allow information disclosure within Ring 0. A network attacker without authentication and with low attack complexity may be able to expose data, with high impact on confidentiality and no impact on integrity or availability. Intel's CVE-specific CVSS 4.0 score is 8.7 (High), and no user interaction is required.
Affected
- Intel(R) TDX Migration Trust Domain (MigTD)
- Exact affected version ranges: Unknown.
Fixed in
Unknown. Check Intel advisory INTEL-SA-01580 for reference software updates.
Workaround
Unknown.
Exploitation
Unknown. No evidence of exploitation was found in the sources reviewed.
Our recommendation
- Check whether any hosts run Intel TDX with live migration of trust domains. Most SMEs are not affected.
- If TDX is in use, apply Intel's reference software update from INTEL-SA-01580 once the affected and fixed versions are confirmed.
- Limit network access to MigTD migration traffic.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
Improper cleanup on thrown exception in the MigTD's SPDM responder for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an information disclosure. Network adversary with an unauthenticated user combined with a low complexity attack may enable data exposure. This result may potentially occur via network access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
