Improper input validation was discovered in UsbCoreDxe in Insyde InsydeH2O kernel 5.4 before 05.47.01, 5.5 before 05.55.01, 5.6 before 05.62.01, and 5.7 before 05.71.01. The SMM module has an SMM call out vulnerability which can be used to write arbitrary memory inside SMRAM and execute arbitrary code at SMM level.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
