Insufficient access control granularity in a subsystem of Intel Xeon 6 Scalable processors with Trust Domain Extensions (TDX) enables cross-domain information disclosure. The flaw, classified under CWE-1220, allows an authenticated local adversary with specialized knowledge of processor internals to leak confidential data belonging to a co-resident trust domain or protected virtual machine, while leaving integrity and availability of all systems untouched. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog, but the CVSS 4.0 scope-change pattern (VC:N/SC:H) signals a meaningful cross-trust-domain confidentiality risk specifically in confidential computing deployments.
