CVE-2026-20705: Information Disclosure in Intel(R) platform
CVE-2026-20705 is an information disclosure vulnerability in the Intel(R) TDX module on some Intel(R) platforms. It involves insecure storage of sensitive information within Ring 0: Trust Domain, potentially allowing a privileged local adversary to expose confidential data. The attack requires high complexity and privileged system software access but no user interaction. The vulnerability impacts confidentiality with no effect on integrity or availability.
AI Analysis
Technical Summary
This vulnerability concerns insecure storage of sensitive information in the Intel(R) TDX module on certain Intel(R) platforms within Ring 0: Trust Domain. A system software adversary with privileged user rights and high attack complexity may disclose sensitive data locally without user interaction or special internal knowledge. The vulnerability affects confidentiality but does not impact integrity or availability. No patch or remediation level is currently indicated, and no known exploits are reported in the wild.
Potential Impact
The vulnerability primarily impacts the confidentiality of the affected system by potentially exposing sensitive information stored insecurely in the Intel TDX module. There is no impact on system integrity or availability. Exploitation requires local privileged access and a high complexity attack, limiting the likelihood of exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been indicated at this time.
