Description:
 The netback driver in Xen, when using certain Linux versions that do not
 allow sleeping in softirq context, allows local guest administrators to
 cause a denial of service ("scheduling while atomic" error and host crash)
 via a malformed packet, which causes a mutex to be taken when trying to
 disable the interface.
Ubuntu-Description:
 Török Edwin discovered a flaw with Xen netback driver when used with Linux
 configurations that do not allow sleeping in softirq context. A guest
 administrator could exploit this flaw to cause a denial of service (system
 crash) on the host.
