High

VectorAV:N/AC:L/Au:N/C:N/I:N/A:C
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.
