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. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023027 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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. IHISI subfunction execution may corrupt SMRAM. An attacker can pass an address in the RCX save state register that overlaps SMRAM, thereby coercing an IHISI subfunction handler to overwrite private SMRAM. • https://www.insyde.com/security-pledge https://www.insyde.com/security-pledge/SA-2023021 • CWE-787: Out-of-bounds Write •

An issue was discovered in ChipsetSvcSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. There is insufficient input validation in BIOS Guard updates. An attacker can induce memory corruption in SMM by supplying malformed inputs to the BIOS Guard SMI handler. • 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-2023020 • 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 •
