CVE-2023-22292

Local privilege escalation via uncaught exception

Published Nov 14, 2023 · Updated Aug 30, 2024

Uncaught exception handling in Intel Unison allows local users with an affected release to escalate privileges through local access. Intel has not published the affected component, triggering input, or code path that leaves the exception uncaught. The local user needs existing low-privileged access; successful exploitation grants higher privileges on the affected device.
