CVE-2022-24350

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 ...

CVE-2022-24350

The CVE-2022-24350 issue affects Insyde InsydeH2O BIOS (IhisiSmm) for kernel 5.0–5.5. The IHISI function 0x17 verifies the output buffer is within the command buffer, but does not ensure that output data does not extend beyond the end of the command buffer. Specifically, GetFlashTable is called o...

CVE-2023-22616

CVE-2023-22616 affects Insyde InsydeH2O BIOS (kernel 5.2–5.5) with the IhisiSmm driver failing to validate the Save State register before use, enabling potential SMRAM corruption due to insufficient input validation. The documents specify the vulnerability and impact but do not provide an explici...

CVE-2023-22613

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...

CVE-2023-22615

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...

CVE-2023-22612

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...
