CVE-2014-0131

Priority
Medium
Description
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.
Ubuntu-Description
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.
