Intel R Trust Domain Extensions Intel R Tdx
Monthly
Insufficient data authenticity verification within Intel Trust Domain Extensions (Intel TDX) at Ring 0 (hypervisor privilege level) enables information disclosure under a high-complexity, locally-mounted attack. A system software adversary already holding hypervisor-level privileges can exploit CWE-345 conditions to expose sensitive Trust Domain memory contents, achieving high confidentiality impact on the vulnerable system with limited integrity effects on both the vulnerable and subsequent systems. No public exploit code exists and this vulnerability has not been listed in CISA KEV, with the vendor-confirmed CVSS 4.0 score of 5.6 (Medium) accurately reflecting the constrained attack profile.
