Description Adam Mariš 2016-03-11 17:13:48 UTC 
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 ati_remote2 kernel module.  The kernel would panic causing null pointer dereference attempting to access a non existent interface descriptor.  The ati_remote2 driver assumes that there will be at least two interface-descriptors with associated endpoint-descriptors.
