CVE-2023-27505

Local privilege escalation via permissive installer defaults

Published Aug 11, 2023 · Updated Oct 10, 2024

Incorrect default permissions in Intel Advanced Link Analyzer Standard Edition installers before 22.1.1 allow local users to escalate privileges. The installers assign overly broad default permissions, but Intel has not identified the affected filesystem object or disclosed how the permissions are abused. Exploitation requires local low-privileged access, high-complexity conditions, and user interaction; success compromises the host account boundary.
