CVE-2014-2580

Priority
Medium
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.
