CVE-2012-5514 [MEDIUM] CVE-2012-5514 kernel: xen: Broken error handling in guest_physmap_mark_populate_on_demand()
CVE-2012-5514 kernel: xen: Broken error handling in guest_physmap_mark_populate_on_demand()
guest_physmap_mark_populate_on_demand(), before carrying out its actual
operation, checks that the subject GFNs are not in use. If that check fails,
the code prints a message and bypasses the gfn_unlock() matching the
gfn_lock() carried out before entering the loop.
A malicious HVM guest administrator can cause Xen to hang.

Red Hat would like to thank the Xen project for reporting this issue.
