| CVE-2022-32470 | 1 Insyde | 1 Insydeh2o | 2026-06-17 | N/A | 7.0 HIGH |
| An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the FwBlockServiceSmm shared buffer used by SMM and non-SMM code could cause TOCTOU race-condition issues that could lead to corruption of SMRAM and escalation of privileges. This attack can be mitigated using IOMMU protection for the ACPI runtime memory used for the command buffer. This attack can be mitigated by copying the firmware block services data to SMRAM before checking it. | |||||

| CVE-2022-24351 | 1 Insyde | 1 Insydeh2o | 2026-06-17 | N/A | 4.7 MEDIUM |
| TOCTOU race-condition vulnerability in Insyde InsydeH2O with Kernel 5.2 before version 05.27.29, Kernel 5.3 before version 05.36.29, Kernel 5.4 version before 05.44.13, and Kernel 5.5 before version 05.52.13 allows an attacker to alter data and code used by the remainder of the boot process. | |||||
| CVE-2022-24350 | 1 Insyde | 1 Insydeh2o | 2026-06-17 | N/A | 5.5 MEDIUM |
| An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. IHISI function 0x17 verifies that the output buffer lies within the command buffer but does not verify that output data does not go beyond the end of the command buffer. In particular, the GetFlashTable function is called directly on the Command Buffer before the DataSize is check, leading to possible circumstances where the data immediately following the command buffer could be destroyed before returning a buffer size error. | |||||
| CVE-2021-41842 | 1 Insyde | 1 Insydeh2o | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in AtaLegacySmm in the kernel 5.0 before 05.08.46, 5.1 before 05.16.46, 5.2 before 05.26.46, 5.3 before 05.35.46, 5.4 before 05.43.46, and 5.5 before 05.51.45 in Insyde InsydeH2O. Code execution can occur because the SMI handler lacks a CommBuffer check. | |||||
| CVE-2020-5956 | 1 Insyde | 1 Insydeh2o | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in SdLegacySmm in Insyde InsydeH2O with kernel 5.1 before 05.15.11, 5.2 before 05.25.11, 5.3 before 05.34.11, and 5.4 before 05.42.11. The software SMI handler allows untrusted external input because it does not verify CommBuffer. | |||||
