CVE-2023-39281

CVE-2023-39281 affects InsydeH2O firmware (AsfSecureBootDxe) with kernel 5.0–5.5. The vulnerability is a stack buffer overflow in AsfSecureBootDxe, enabling arbitrary code execution during the DXE phase. Public sources in the connected documents confirm the affected software/component and the roo...

CVE-2023-30633

An issue was discovered in TrEEConfigDriver in Insyde InsydeH2O with kernel 5.0 through 5.5. It can report false TPM PCR values, and thus mask malware activity. Devices use Platform Configuration Registers PCRs to record information about device and software configuration to ensure that the boot...

Design/Logic Flaw

An issue was discovered in TrEEConfigDriver in Insyde InsydeH2O with kernel 5.0 through 5.5. It can report false TPM PCR values, and thus mask malware activity. Devices use Platform Configuration Registers PCRs to record information about device and software configuration to ensure that the boot...

CVE-2023-30633

CVE-2023-30633 affects Insyde InsydeH2O’s TrEEConfigDriver (kernel 5.0–5.5). The issue allows reporting of false TPM PCR values, enabling a device to masquerade as healthy by extending arbitrary data into PCR banks. Impact depends on PCR integrity, potentially masking malware activity; exploit re...

Siemens InsydeH2O Privilege Escalation (CVE-2020-5955)

An issue was discovered in Int15MicrocodeSmm in Insyde InsydeH2O before 2021-10-14 on Intel client chipsets. A caller may be able to escalate privileges. Insyde BIOS is typically used in RUGGEDCOM APE products and some SIMATIC devices. Please refer to the vendor advisory for a precise list of...

Siemens InsydeH2O Improper Restriction of Operations within the Bounds of a Memory Buffer (CVE-2021-41838)

An issue was discovered in SdHostDriver in the kernel 5.0 through 5.5 in Insyde InsydeH2O. There is an SMM callout that allows an attacker to access the System Management Mode and execute arbitrary code. This occurs because of a Numeric Range Comparison Without a Minimum Check. Insyde BIOS is...

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.
