Doc Text:
A flaw was found in migtd. An integer overflow vulnerability in the virtual socket (vsock) communication interface allows an authenticated local attacker to trigger a Denial of Service (DoS). By exploiting this flaw within the hypervisor, an attacker can disrupt system operations and crash the migration domain.

Description OSIDB Bzimport 2026-11-10 20:12:24 UTC 
Integer overflow in the MigTD vsock for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local 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 (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
