CVE-2016-4951

Priority
Description
The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel
through 4.6 does not verify socket existence, which allows local users to
cause a denial of service (NULL pointer dereference and system crash) or
possibly have unspecified other impact via a dumpit operation.
Ubuntu-Description
Baozeng Ding discovered that the Transparent Inter-process Communication
(TIPC) implementation in the Linux kernel did not verify socket existence
before use in some situations. A local attacker could use this to cause a
denial of service (system crash).
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
linux-lts-saucy no longer receives official support
