CVE-2021-41840 1 Insyde 1 Insydeh2o 2025-11-04 8.2 High
An issue was discovered in NvmExpressDxe in the kernel 5.0 through 5.5 in Insyde InsydeH2O. There is an SMM callout that allows an attacker to access the System Management Mode and execute arbitrary code. This occurs because of Inclusion of Functionality from an Untrusted Control Sphere.
CVE-2021-41839 1 Insyde 1 Insydeh2o 2025-11-04 8.2 High
An issue was discovered in NvmExpressDxe in the kernel 5.0 through 5.5 in Insyde InsydeH2O.

CVE-2021-33627 2 Insyde, Siemens 29 Insydeh2o, Simatic Field Pg M5, Simatic Field Pg M5 Firmware and 26 more 2025-11-04 8.2 High
An issue was discovered in Insyde InsydeH2O Kernel 5.0 before 05.09.11, 5.1 before 05.17.11, 5.2 before 05.27.11, 5.3 before 05.36.11, 5.4 before 05.44.11, and 5.5 before 05.52.11 affecting FwBlockServiceSmm. Software SMI services that use the Communicate() function of the EFI_SMM_COMMUNICATION_PROTOCOL do not check whether the address of the buffer is valid, which allows use of SMRAM, MMIO, or OS kernel addresses.
CVE-2021-33626 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Apr1808, Ruggedcom Apr1808 Firmware and 30 more 2025-11-04 7.8 High
A vulnerability exists in SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer(QWORD values for CommBuffer). This can be used by an attacker to corrupt data in SMRAM memory and even lead to arbitrary code execution.
CVE-2021-33625 3 Insyde, Netapp, Siemens 34 Insydeh2o, Fas\/aff Bios, Ruggedcom Ape1808 and 31 more 2025-11-04 7.5 High
An issue was discovered in Kernel 5.x in Insyde InsydeH2O, affecting HddPassword. Software SMI services that use the Communicate() function of the EFI_SMM_COMMUNICATION_PROTOCOL do not check whether the address of the buffer is valid, which allows use of SMRAM, MMIO, or OS kernel addresses.
CVE-2020-5953 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Ape1808, Ruggedcom Ape1808 Firmware and 30 more 2025-11-04 7.5 High
A vulnerability exists in System Management Interrupt (SWSMI) handler of InsydeH2O UEFI Firmware code located in SWSMI handler that dereferences gRT (EFI_RUNTIME_SERVICES) pointer to call a GetVariable service, which is located outside of SMRAM. This can result in code execution in SMM (escalating privilege from ring 0 to ring -2).
CVE-2020-27339 2 Insyde, Siemens 33 Insydeh2o, Ruggedcom Apr1808, Ruggedcom Apr1808 Firmware and 30 more 2025-11-04 6.7 Medium
In the kernel in Insyde InsydeH2O 5.x, certain SMM drivers did not correctly validate the CommBuffer and CommBufferSize parameters, allowing callers to corrupt either the firmware or the OS memory. The fixed versions for this issue in the AhciBusDxe, IdeBusDxe, NvmExpressDxe, SdHostDriverDxe, and SdMmcDeviceDxe drivers are 05.16.25, 05.26.25, 05.35.25, 05.43.25, and 05.51.25 (for Kernel 5.1 through 5.5).
CVE-2024-55567 1 Insyde 1 Insydeh2o 2025-08-20 7.5 High
Improper input validation was discovered in UsbCoreDxe in Insyde InsydeH2O kernel 5.4 before 05.47.01, 5.5 before 05.55.01, 5.6 before 05.62.01, and 5.7 before 05.71.01. The SMM module has an SMM call out vulnerability which can be used to write arbitrary memory inside SMRAM and execute arbitrary code at SMM level.
CVE-2024-52877 1 Insyde 1 Insydeh2o 2025-08-15 7.5 High
An issue was discovered in Insyde InsydeH2O kernel 5.2 before version 05.29.50, kernel 5.3 before version 05.38.50, kernel 5.4 before version 05.46.50, kernel 5.5 before version 05.54.50, kernel 5.6 before version 05.61.50, and kernel 5.7 before version 05.70.50. In VariableRuntimeDxe driver, callback function SmmCreateVariableLockList () calls CreateVariableLockListInSmm (). In CreateVariableLockListInSmm (), it uses StrSize () to get variable name size and it could lead to a buffer over-read.
CVE-2024-52878 1 Insyde 1 Insydeh2o 2025-08-15 7.5 High
An issue was discovered in Insyde InsydeH2O kernel 5.2 before version 05.29.50, kernel 5.3 before version 05.38.50, kernel 5.4 before version 05.46.50, kernel 5.5 before version 05.54.50, kernel 5.6 before version 05.61.50, and kernel 5.7 before version 05.70.50. In VariableRuntimeDxe driver, VariableServicesSetVariable () can be called by gRT_>SetVariable () or the SmmSetSensitiveVariable () or SmmInternalSetVariable () from SMM. In VariableServicesSetVariable (), it uses StrSize () to get variable name size, uses StrLen () to get variable name length and uses StrCmp () to compare strings. These actions may cause a buffer over-read.
