CVE-2020-24088

Local privilege escalation via MmMapIoSpace driver routine

Published Sep 11, 2023 · Updated Sep 26, 2024

Privilege escalation in Foxconn FOX LiveUpdate 2.1.6.26 allows local users to gain elevated privileges through its Windows driver. The public record identifies the driver's MmMapIoSpace routine as the vulnerable locus but does not disclose how attacker-controlled input is validated or mapped. A low-privileged local account and no user interaction are required, and successful exploitation compromises system confidentiality, integrity, and availability.
