CVE-2021-45971

CVE-2021-45971 affects InsydeH2O’s SdHostDriver in the SMM path. A SWSMI handler registers without adequately validating the CommBufferData buffer, enabling potential SMM memory corruption and, per sources, possible code execution within SMM. Affected kernels: 5.1 before 05.16.25, 5.2 before 05.2...

CVE-2021-41842

CVE-2021-41842 affects Insyde InsydeH2O firmware (AtaLegacySmm) with kernels 5.0–5.5; vulnerability arises from SMI handler lacking a CommBuffer check, enabling potential code execution. Confirmed affected versions are before 05.08.46 (5.0), before 05.16.46 (5.1), before 05.26.46 (5.2), before 05...

CVE-2021-45969

CVE-2021-45969 describes a vulnerability in the InsydeH2O firmware’s SMM path (AhciBusDxe) where the SWSMI handler registers a buffer pointer without proper validation, specifically the CommBuffer+8 location. This allows an attacker with local access to trigger memory corruption in System Managem...

CVE-2021-45970

An issue was discovered in IdeBusDxe in Insyde InsydeH2O with kernel 5.1 before 05.16.25, 5.2 before 05.26.25, 5.3 before 05.35.25, 5.4 before 05.43.25, and 5.5 before 05.51.25.
