InsydeH2O BIOS 5.0-5.5: SMM Mem Corrupt via Malformed RCX Pointer in IhisiSmm
CVE-2023-22613
8.8 - High
- April 11, 2023
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.
Memory Corruption
InsydeH2O IHISI SMRAM Overwrite 5.0-5.5
CVE-2023-22615
8.4 - High
- April 11, 2023
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.
