CVE-2014-1444

Published: 18 January 2014

The fst_get_iface function in drivers/net/wan/farsync.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCWANDEV ioctl call.

From the Ubuntu security team

An information leak was discovered in the Linux kernel's SIOCWANDEV ioctl call. A local user with the CAP_NET_ADMIN capability could exploit this flaw to obtain potentially sensitive information from kernel memory.
