A flaw was found in in the Linux kernel's USB device management code which could cause a crash when a device which required sndusbaudio driver. The kernel would panic causing null pointer dereference attempting to access non existent endpoints.

A use after free vulnerability was found in pppunregisterchannel function. This is triggered when network namespace is removed while pppasync channel is still registered in it and pppunregisterchannel() tries to access its per-netns data in the defunct namespace.
An attacker who could control this memory that is being used in the defunct namespace could create a denial of service by spinlocking a CPU.
An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.

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.
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.
