CVE-2015-4004

Published: 7 June 2015

The OZWPAN driver in the Linux kernel through 4.0.5 relies on an untrusted length field during packet parsing, which allows remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read and system crash) via a crafted packet.

From the Ubuntu Security Team

Jason A. Donenfeld discovered multiple out-of-bounds reads in the OZMO USB over wifi device drivers in the Linux kernel. A remote attacker could use this to cause a denial of service (system crash) or obtain potentially sensitive information from kernel memory.

Notes

android kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
linux-lts-saucy no longer receives official support
linux-lts-quantal no longer receives official support

it seems that upstream gave up and ripped this driver out en-toto:
