Doc Text:
A flaw was found in the virtio-serial driver of the Intel Trust Domain Extensions Migration Trust Domain (MigTD). A local privileged attacker can exploit this vulnerability through operations that fail to properly release memory after its use. Over time, this unreleased memory can deplete system resources, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-10 19:34:03 UTC 
Missing release of memory after effective lifetime in the MigTD virtio-serial driver for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. System software adversary with a privileged user combined with a low 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 (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
