CVE-2022-27499

Information disclosure via premature resource release

Published Nov 11, 2022 · Updated Feb 5, 2025

Resource lifetime error in Intel SGX SDK before 2.18.100.1 on Linux and 2.17.100.1 on Windows allows local users to read information. Intel identifies premature resource release during its expected lifetime, but does not disclose the affected component or the resource and operation involved. Exploitation requires high privileges, local access, no user interaction, and a high-complexity condition; the published impact is limited to information disclosure.
