03 Feb 2022 — An issue was discovered in Kernel 5.x in Insyde InsydeH2O, affecting HddPassword. Software SMI services that use the Communicate() function of the EFI_SMM_COMMUNICATION_PROTOCOL do not check whether the address of the buffer is valid, which allows use of SMRAM, MMIO, or OS kernel addresses. Se ha descubierto un problema en el Kernel versión 5.x de InsydeH2O, que afecta a HddPassword. Los servicios SMI de software que utilizan la función Communicate() del EFI_SMM_COMMUNICATION_PROTOCOL no comprueban si la di... • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

03 Feb 2022 — A vulnerability exists in System Management Interrupt (SWSMI) handler of InsydeH2O UEFI Firmware code located in SWSMI handler that dereferences gRT (EFI_RUNTIME_SERVICES) pointer to call a GetVariable service, which is located outside of SMRAM. This can result in code execution in SMM (escalating privilege from ring 0 to ring -2). Se presenta una vulnerabilidad en el manejador de Interrupciones de administración del Sistema (SWSMI) del código del Firmware UEFI de InsydeH2O ubicado en el manejador SWSMI que... • https://cert-portal.siemens.com/productcert/pdf/ssa-306654.pdf •

01 Oct 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.
