bugzilla·2012-11-16·CVSS 4.7
CVE-2012-5515 [MEDIUM] CVE-2012-5515 kernel: xen: Several memory hypercall operations allow invalid extent order values
CVE-2012-5515 kernel: xen: Several memory hypercall operations allow invalid extent order values
Allowing arbitrary extent_order input values for XENMEM_decrease_reservation,
XENMEM_populate_physmap, and XENMEM_exchange can cause arbitrarily long time
being spent in loops without allowing vital other code to get a chance to
execute. This may also cause inconsistent state resulting at the completion
of these hypercalls.
A malicious guest administrator can cause Xen to hang.
Versions of Xen that do not support supporting Populate-on-Demand may
only be theoretically affected.
Acknowledgements:
Red Hat would like to thank the Xen project for reporting this issue.
Discussion:
Please note that we do not support Populate-on-Demand in Xen hypervisor as shipped with Red Hat Enterprise Linux
