CVE-2016-4486 (retired)

Priority
Description
The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux
kernel before 4.5.5 does not initialize a certain data structure, which
allows local users to obtain sensitive information from kernel stack memory
by reading a Netlink message.
Ubuntu-Description
Kangjie Lu discovered an information leak in the routing netlink socket
interface (rtnetlink) implementation in the Linux kernel. A local attacker
could use this to obtain potentially sensitive information from kernel
memory.
Notes
