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 •

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. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023002 • 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. An SMM memory corruption vulnerability in the FvbServicesRuntimeDxe driver allows an attacker to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges to SMM. Se ha detectado un problema en Insyde InsydeH2O con el kernel versiones 5.0 hasta 5.5. Una vulnerabilidad de corrupción de memoria SMM en el controlador FvbServicesRuntimeDxe permite a un atacante escribir datos fijos o predecibles en la SMRAM. • https://binarly.io/advisories/BRLY-2022-026/index.html https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2022035 • CWE-20: Improper Input Validation •
