DMA attacks on the SdHostDriver buffer used by SMM and non-SMM code could cause TOCTOU race-condition issues that could lead to corruption of SMRAM and escalation of privileges. This attack can be mitigated by using IOMMU protection for the ACPI runtime memory used for the command buffer. This attack can be mitigated by copying the link data to SMRAM before checking it and verifying that all pointers are within the buffer."}, {"lang": "es", "value": "Se descubri\u00f3 un problema en Insyde InsydeH2O con los kernels 5.0 a 5.5.
