CVE-2024-25078

SMM privilege escalation via untrusted pointer dereference

Published May 15, 2024 · Updated Feb 13, 2025

Memory corruption in InsydeH2O StorageSecurityCommandDxe allows local users with high privileges to escalate into SMM. The published CWE identifies an untrusted pointer dereference, but public records do not identify the pointer or specific unsafe memory operation. Exploitation requires high-complexity local conditions; success crosses into SMM, exposing protected confidentiality and integrity and enabling limited service interruption.
