CVE-2023-28823

Local privilege escalation via uncontrolled search path

Published Aug 11, 2023 · Updated Oct 15, 2024

Uncontrolled search path in Intel oneAPI installers before 4.3.1.493 allows local users to escalate privileges during installation. Intel identifies installer search-path handling as the locus but does not disclose which path element, file, or loading operation accepts attacker-controlled input. Exploitation requires authenticated low-privileged local access and user interaction with an affected installer.
