CVE-2018-19964
An issue was discovered in Xen 4.11.x allowing x86 guest OS users to cause a denial of service (host OS hang) because the p2m lock remains unavailable indefinitely in certain error conditions.
Does this matter?
Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.
