CVE-2014-0131

Published: 24 March 2014

Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation.

From the Ubuntu security team

Michael S. Tsirkin discovered an information leak in the Linux kernel's segmentation of skbs when using the zerocopy feature of vhost-net. A local attacker could exploit this flaw to gain potentially sensitive information from kernel memory.
