Siemens InsydeH2O Time-of-check Time-of-use Race Condition (CVE-2022-34325)

DMA transactions which are targeted at input buffers used for the StorageSecurityCommandDxe software SMI handler could cause SMRAM corruption through a TOCTOU attack. DMA transactions which are targeted at input buffers used for the software SMI handler used by the StorageSecurityCommandDxe drive...

Siemens InsydeH2O Improper Input Validation (CVE-2021-41842)

An issue was discovered in AtaLegacySmm in the kernel 5.0 before 05.08.46, 5.1 before 05.16.46, 5.2 before 05.26.46, 5.3 before 05.35.46, 5.4 before 05.43.46, and 5.5 before 05.51.45 in Insyde InsydeH2O. Code execution can occur because the SMI handler lacks a CommBuffer check. Insyde BIOS is...

Siemens InsydeH2O Out-of-bounds Write (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. Insyde BIOS is typically...

Siemens InsydeH2O Improper Input Validation (CVE-2020-5956)

An issue was discovered in SdLegacySmm in Insyde InsydeH2O with kernel 5.1 before 05.15.11, 5.2 before 05.25.11, 5.3 before 05.34.11, and 5.4 before 05.42.11. The software SMI handler allows untrusted external input because it does not verify CommBuffer. Insyde BIOS is typically used in RUGGEDCOM...

Siemens InsydeH2O Out-of-bounds Write (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. Insyde BIOS is typically used in RUGGEDCOM APE products and some SIMATIC devices. Please refer...
