Intel MigTD: Improper resource lifetime handling in TLS client
Summary
The TLS client of the Intel TDX Migration Trust Domain (MigTD) does not properly control a resource through its lifetime. According to the CVE description, a hypervisor may trigger a denial of service, and a network adversary without credentials or user interaction may cause data corruption. CVSS 4.0 base score is 5.3 (Medium); the vector specifies adjacent access, while the description says network access, so the exact reachability is unclear.
Affected
- Intel TDX Migration Trust Domain (MigTD), versions per Intel advisory INTEL-SA-01580
- Exact affected versions: Unknown. The CVE record refers to "See references" and lists the default status as unaffected.
Fixed in
Unknown. Intel has released reference software updates in advisory INTEL-SA-01580; the specific fixed versions were not verified.
Workaround
Unknown. No vendor-stated workaround was identified.
Exploitation
- Not known to be exploited in the wild.
- Not listed in CISA KEV according to aggregators.
- No public proof-of-concept identified.
Our recommendation
- Check INTEL-SA-01580 for affected and fixed MigTD versions.
- If you operate Intel TDX hosts with MigTD-based live migration (private cloud, hosting), apply firmware and TDX module updates through your server vendor.
- Standard SME servers and cloud workloads are unlikely to be affected; verify this in your inventory.
- Monitor the CVE record and Intel advisory for updates.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
Improper control of a resource through its lifetime in the MigTD's TLS client for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable data corruption. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
