Published May 3, 2013
7.8
HIGHCVSS 2.0
EPSS 4.19%
Description
The veth (aka virtual Ethernet) driver in the Linux kernel before 2.6.34 does not properly manage skbs during congestion, which allows remote attackers to cause a denial of service (system crash) by leveraging lack of skb consumption in conjunction with a double-free error.
