CVE-2026-62930 · Severity: info · Published 2026-11-10

Intel's TDX Migration Trust Domain (MigTD) is a hypervisor component that enables secure virtual machine migration in Intel processors. An unchecked return value in its TLS implementation allows a network-based adversary to trigger a denial of service, potentially disrupting critical virtualized infrastructure.

Technologies: [Intel TDX Migration Trust Domain (MigTD)](https://junglewise.ai/threats/technologies/tdx-migration-trust-domain-migtd). Vendors: [Intel](https://junglewise.ai/threats/vendors/intel).

## Quick answers

**Is CVE-2026-62930 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-62930 being exploited in the wild.

**How severe is CVE-2026-62930?** Informational severity, published 10 November 2026.

**Which products and versions are affected?** Intel TDX Migration Trust Domain (MigTD).

**Is there a fix for CVE-2026-62930?** No fixed version is recorded yet. Check the vendor's advisory in the references below. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.

**How is CVE-2026-62930 attacked?** It is attacked over the network or from the adjacent network, in device firmware.

**Am I affected by CVE-2026-62930?** Check whether you run Intel TDX Migration Trust Domain (MigTD). Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

An unchecked return value in MigTD's TLS transport implementation fails to validate cryptographic or connection operations, allowing improper state transitions or resource exhaustion. Attack via adjacent network access from an unauthenticated attacker with low complexity can trigger availability loss. The vulnerability affects integrity (low) and availability (low) with low confidence in actual impact severity, as rating contradictions appear in the advisory text.
