A vulnerability was found in Linux kernel. There is an information leak in file "sound/core/timer.c" of the latest mainline Linux kernel, the stack object “tread” has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copytouser(), resulting a kernel leak.

Destroy of network interface with huge number of ipv4 addresses keeps rtnllock for a very long time (up to hour). It blocks many network related operations, including for example creation of new incoming ssh connections.
The problem is especially important for containers, container owner have enough permission to enable this trigger and then can block network access on whole host node.

This was assigned CVE-2016-2186 by Red Hat.
A flaw was found in in the Linux kernel's USB device management code which could cause a kernel panic when a device which required atiremote2 kernel module. The kernel would panic causing null pointer dereference attempting to access a non existent interface descriptor. The atiremote2 driver assumes that there will be at least two interface-descriptors with associated endpoint-descriptors.

fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes.
