CVE-2022-32955
https://notcve.org/view.php?id=CVE-2022-32955
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the NvmExpressDxe 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 by using IOMMU protection for the ACPI runtime memory used for the command buffer. This attack can be mitigated by copying the link data to SMRAM before checking it and verifying that all pointers are within the buffer. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023015 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the HddPassword 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 https://www.insyde.com/security-pledge/SA-2023005 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

CVE-2022-32471
https://notcve.org/view.php?id=CVE-2022-32471
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 https://www.insyde.com/security-pledge/SA-2023003 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
