The following security bugs were fixed:
– CVE-2015-7566: The treo_attach function in drivers/usb/serial/visor.c in
the Linux kernel allowed physically proximate attackers to cause a
denial of service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by inserting a USB device that
lacks a (1) bulk-in or (2) interrupt-in endpoint (bnc#961512).

service (NULL pointer dereference and host OS crash) by leveraging a
system with access to a passed-through MSI or MSI-X capable physical PCI
device and a crafted sequence of XEN_PCI_OP_* operations, aka “Linux
