CVE-2022-32266 is a Time-of-Check to Time-of-Use (TOCTOU) vulnerability affecting Insyde InsydeH2O kernels 5.0 through 5.5, specifically within the PcdSmmDxe driver. It allows for DMA attacks on the parameter buffer of a software SMI handler, potentially corrupting ACPI fields and adjacent memory. Rated Medium (CVSS 6.4), exploitation requires high privileges and detailed knowledge of the platform's PCD database, but could lead to high confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not on the KEV catalog.
