CVE-2018-3658
Multiple memory leaks in Intel AMT in Intel CSME firmware versions before 12.0.5 may allow an unauthenticated user with Intel AMT provisioned to potentially cause a partial denial of service via network access.
Does this matter?
Lower severity and a low EPSS score (3.33%). Track it; it rarely justifies an emergency change on its own.
