**Name of the Vulnerable Software and Affected Versions**
Xen (affected versions not specified)
**Description**
The issue is related to the processing of transmit requests in Xen's virtual network protocol, which can consist of multiple parts. When all parts of a particular request are of zero length, it can lead to a de-reference of NULL in core networking code. This can potentially cause a denial of service. The `xenvif get requests()` function in the `drivers/net/xen-netback/netback.c` module is associated with this issue.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
