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 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 •
