CVE-2016-5243 (retired)

Priority
Description
The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the
Linux kernel through 4.6.3 does not properly copy a certain string, 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 netlink implementation of
the Linux kernel. A local attacker could use this to obtain sensitive
information from kernel memory.
