CVE-2014-2580

Publication date 15 April 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

From the Ubuntu Security Team

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.
