A LogoFAIL issue was discovered in BmpDecoderDxe in Insyde InsydeH2O with kernel 5.2 before 05.28.47

CVE-2023-40238 5.5 - Medium - December 07, 2023

A LogoFAIL issue was discovered in BmpDecoderDxe in Insyde InsydeH2O with kernel 5.2 before 05.28.47, 5.3 before 05.37.47, 5.4 before 05.45.47, 5.5 before 05.53.47, and 5.6 before 05.60.47 for certain Lenovo devices. Image parsing of crafted BMP logo files can copy data to a specific address during the DXE phase of UEFI execution. This occurs because of an integer signedness error involving PixelHeight and PixelWidth during RLE4/RLE8 compression.

An SMM memory corruption vulnerability in the SMM driver (SMRAM write) in CsmInt10HookSmm in Insyde InsydeH2O with kernel 5.0 through 5.5

CVE-2023-39283 7.8 - High - November 02, 2023

An issue was discovered in TrEEConfigDriver in Insyde InsydeH2O with kernel 5.0 through 5.5

CVE-2023-30633 5.3 - Medium - October 19, 2023

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 process is secure. (For example, Windows uses these PCR measurements to determine device health.) A vulnerable device can masquerade as a healthy device by extending arbitrary values into Platform Configuration Register (PCR) banks. This requires physical access to a target victim's device, or compromise of user credentials for a device. This issue is similar to CVE-2021-42299 (on Surface Pro devices).

An issue was discovered in SystemFirmwareManagementRuntimeDxe in Insyde InsydeH2O with kernel 5.0 through 5.5

CVE-2023-34195 7.8 - High - September 18, 2023

An issue was discovered in SystemFirmwareManagementRuntimeDxe in Insyde InsydeH2O with kernel 5.0 through 5.5. The implementation of the GetImage method retrieves the value of a runtime variable named GetImageProgress, and later uses this value as a function pointer. This variable is wiped out by the same module near the end of the function. By setting this UEFI variable from the OS to point into custom code, an attacker could achieve arbitrary code execution in the DXE phase, before several chipset locks are set.

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5

CVE-2022-24350 5.5 - Medium - April 12, 2023

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 is called directly on the Command Buffer before the DataSize is check, leading to possible circumstances where the data immediately following the command buffer could be destroyed before returning a buffer size error.

In UsbCoreDxe, tampering with the contents of the USB working buffer using DMA while certain USB transactions are in process leads to a TOCTOU problem that could be used by an attacker to cause SMRAM corruption and escalation of privileges The UsbCoreDxe module creates a working buffer for USB transactions outside of SMRAM. The code which uses can be inside of SMM, making the working buffer untrusted input. The buffer can be corrupted by DMA transfers. The SMM code code attempts to sanitize pointers to ensure all pointers refer to the working buffer, but when a pointer is not found in the list of pointers to sanitize, the current action is not aborted, leading to undefined behavior.

An issue was discovered in SdLegacySmm in Insyde InsydeH2O with kernel 5.1 before 05.15.11

CVE-2020-5956 7.5 - High - January 05, 2022

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.

Improper Input Validation

NetworkPkg/IScsiDxe has remotely exploitable buffer overflows.

CVE-2021-38575 8.1 - High - December 01, 2021

NetworkPkg/IScsiDxe has remotely exploitable buffer overflows.

Buffer Overflow

A vulnerability exists in SMM (System Management Mode) branch

CVE-2021-33626 7.8 - High - October 01, 2021

A vulnerability exists in SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer(QWORD values for CommBuffer). This can be used by an attacker to corrupt data in SMRAM memory and even lead to arbitrary code execution.

Inclusion of Functionality from Untrusted Control Sphere

In the kernel in Insyde InsydeH2O 5.x, certain SMM drivers did not correctly validate the CommBuffer and CommBufferSize parameters

CVE-2020-27339 6.7 - Medium - June 16, 2021

In the kernel in Insyde InsydeH2O 5.x, certain SMM drivers did not correctly validate the CommBuffer and CommBufferSize parameters, allowing callers to corrupt either the firmware or the OS memory. The fixed versions for this issue in the AhciBusDxe, IdeBusDxe, NvmExpressDxe, SdHostDriverDxe, and SdMmcDeviceDxe drivers are 05.16.25, 05.26.25, 05.35.25, 05.43.25, and 05.51.25 (for Kernel 5.1 through 5.5).

Improper Input Validation

Improper access control in the Insyde software tools may

CVE-2019-12532 7.8 - High - August 26, 2019

Improper access control in the Insyde software tools may allow an authenticated user to potentially enable escalation of privilege, or information disclosure via local access. This is a software vulnerability, not a firmware issue. Affected tools include: H2OFFT version 3.02~5.28, 100.00.00.00~100.00.08.23 and 200.00.00.01~200.00.00.05, H2OOAE before version 200.00.00.02, H2OSDE before version 200.00.00.07, H2OUVE before version 200.00.02.02, H2OPCM before version 100.00.06.00, H2OELV before version 100.00.02.08.
