104 CVEs affecting Insyde products, tracked from the National Vulnerability Database, with CVSS/EPSS scores and exploitation status.
Most Affected Products
An issue was discovered in AhciBusDxe in Insyde InsydeH2O with kernel 5.1 before 05.16.25, 5.2 before 05.26.25, 5.3 before 05.35.25, 5.4 before 05.43.25, and 5.5 before 05.51.25. A vulnerability exists in the SMM (System Management Mode) branch that registers a SWSMI handler that does not sufficiently check or validate the allocated buffer pointer (the CommBuffer+8 location).
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.
NetworkPkg/IScsiDxe has remotely exploitable buffer overflows.
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.
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.
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 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.
Insyde BIOS V190 does not clear the keyboard buffer after reading the BIOS password during system startup, which allows local administrators or users to read the password directly from physical memory.
