CVE-2022-30773
DMA attacks on the parameter buffer used by the IhisiSmm driver could change the contents after parameter values have been checked but before they are used (a TOCTOU attack).
Does this matter?
Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.
