CVE-2024-21801

Denial of service via undisclosed control-flow flaw

Published Aug 14, 2024 · Updated Aug 16, 2024

Insufficient control-flow management in Intel TDX Module before 1.5.05.46.698 allows local users to cause denial of service. Intel has not disclosed the affected control-flow locus, the triggering operation, or whether the interruption causes a hang, crash, or reboot. Exploitation requires privileged local access and can interrupt TDX-protected workload availability; no integrity effect is reported by Intel's CVSS 3.1 assessment.
