An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The FwBlockSericceSmm driver does not properly validate input parameters for a software SMI routine, leading to memory corruption of arbitrary addresses including SMRAM, and possible arbitrary code execution.
Add your gear to cvedb and we'll alert you only when insyde ships something exploited.
