# Intel TDX MigTD: shared-memory race lets a privileged attacker corrupt data

Link for people: https://infrastack.ai/live/CVE-2026-49036 (this .md is for agents)

Intel's TDX Migration Trust Domain (MigTD) has a time-of-check time-of-use race in its shared memory, so a privileged system-software attacker can corrupt data or cause a denial of service. The flaw is reachable only locally and needs no user interaction.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Time-of-check time-of-use race condition in the MigTD shared memory 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 data corruption. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
