CVE-2023-28658

Local privilege escalation via inherited permissions

Published Aug 11, 2023 · Updated Oct 15, 2024

Insecure inherited permissions in Intel oneMKL before 2022.0 allow local users to escalate privileges through local access. Intel has not published the affected file, directory, or installation operation that inherits unsafe permissions. Reaching the flaw requires low-privileged local access and user interaction, and successful exploitation grants higher privileges.
