Doc Text:
A flaw was found in the virtio driver of Intel Trust Domain Extensions Migration Trust Domain (MigTD). A use-after-free vulnerability occurs when the driver accesses memory after it has been released. A local privileged attacker can exploit this flaw to cause memory corruption, potentially leading to privilege escalation.

Description OSIDB Bzimport 2026-11-10 19:21:14 UTC 
Use after free in the MigTD virtio driver for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable data corruption. 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 (high) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
