NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-xen-devel package and not the kernel-xen-devel package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability."
