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 •
