Hello,

Linux kernel built with the ChipIdia Highspeed Dual Role
Controller (CONFIG_USB_CHIPIDEA) along with the ChipIdea host
controller (CONFIG_USB_CHIPIDEA_HOST) modules, is vulnerable to a
kernel crash. It occurs while streaming content over network via
USB/Ethernet adapter

A user/program could use this flaw to crash the kernel resulting in
DoS.

Please use CVE-2013-2058 for this issue.

JFYI, the respective code was added in Linux 3.5 as far as I see.

And given the hardware involved, I really doubt any desktop/server
distro ever enabled the driver.  Or if they did, I doubt they had any
users with this hardware present, it's an embedded USB controller core,
so maybe a few Android systems might have it present.

thanks,
