12 Apr 2023 — 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 erro... • https://www.insyde.com/security-pledge • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

15 Feb 2023 — An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the PnpSmm 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. • https://www.insyde.com/security-pledge • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

15 Feb 2023 — An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. The IhisiDxe driver uses the command buffer to pass input and output data. By modifying the command buffer contents with DMA after the input parameters have been checked but before they are used, the IHISI SMM code may be convinced to modify SMRAM or OS, leading to possible data corruption or escalation of privileges. • https://www.insyde.com/security-pledge • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
