CVE-2016-9806 (retired)

Priority
Description
Race condition in the netlink_dump function in net/netlink/af_netlink.c in
the Linux kernel before 4.6.3 allows local users to cause a denial of
service (double free) or possibly have unspecified other impact via a
crafted application that makes sendmsg system calls, leading to a free
operation associated with a new dump that started earlier than anticipated.
Ubuntu-Description
Baozeng Ding discovered a double free in the netlink_dump() function in the
Linux kernel. A local attacker could use this to cause a denial of service
(system crash).
