CVE-2016-3951 (retired)

Priority
Description
Double free vulnerability in drivers/net/usb/cdc_ncm.c in the Linux kernel
before 4.5 allows physically proximate attackers to cause a denial of
service (system crash) or possibly have unspecified other impact by
inserting a USB device with an invalid USB descriptor.
Ubuntu-Description
Andrey Konovalov discovered that the CDC Network Control Model USB driver
in the Linux kernel did not cancel work events queued if a later error
occurred, resulting in a use-after-free. An attacker with physical access
could use this to cause a denial of service (system crash).
Notes
 jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
  not supported on the Ubuntu Touch 14.10 and earlier preview kernels
 jdstrand> linux-lts-saucy no longer receives official support
 jdstrand> linux-lts-quantal no longer receives official support
 sbeattie> requires physical proximity
