https://notcve.org/view.php?id=CVE-2023-22616
An issue was discovered in Insyde InsydeH2O with kernel 5.2 through 5.5. The Save State register is not checked before use. The IhisiSmm driver does not check the value of a save state register before use. Due to insufficient input validation, an attacker can corrupt SMRAM. • https://research.nccgroup.com/2023/04/11/stepping-insyde-system-management-mode https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023022 • CWE-610: Externally Controlled Reference to a Resource in Another Sphere •

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. A malicious host OS can invoke an Insyde SMI handler with malformed arguments, resulting in memory corruption in SMM. • https://research.nccgroup.com/2023/04/11/stepping-insyde-system-management-mode https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023019 • CWE-787: Out-of-bounds Write •

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. It is possible to write to an attacker-controlled address. An attacker could invoke an SMI handler with a malformed pointer in RCX that overlaps SMRAM, resulting in SMM memory corruption. • https://research.nccgroup.com/2023/04/11/stepping-insyde-system-management-mode https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023023 • CWE-787: Out-of-bounds Write •

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. DMA attacks on the SdHostDriver 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-2023013 • 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 IdeBusDxe 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-2023010 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
