CVE-2023-22612

CVE-2023-22612 affects InsydeH2O firmware’s IhisiSmm component. The issue exists on InsydeH2O builds with kernels 5.0–5.5, where a malicious host OS can invoke the Insyde SMI handler with malformed arguments, leading to memory corruption in System Management Mode (SMM). Connected sources describe...

CVE-2023-22614

CVE-2023-22614 affects InsydeH2O (ChipsetSvcSmm) with kernel 5.0–5.5. The root cause is insufficient input validation in BIOS Guard updates, allowing a malformed BIOS Guard SMI to trigger memory corruption in SMM. The vulnerability is described across multiple sources (NVD, Red Hat, Tenable plugi...

CVE-2023-22615

CVE-2023-22615 affects Insyde InsydeH2O’s IhisiSmm subsystem (kernel 5.0–5.5). The root cause is a flaw in IHISI state handling that allows an attacker to pass an address in the RCX save state register that overlaps SMRAM, causing an IHISI subfunction handler to overwrite private SMRAM. This can ...
