CVE-2013-2058 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2058): The host_start function in drivers/usb/chipidea/host.c in the Linux kernel before 3.7.4 does not properly support a certain non-streaming option, which allows local users to cause a denial of service (system crash) by sending a large amount of network traffic through a USB/Ethernet adapter. Fix in 3.8 onwards |
From ${URL} : 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 could occur while streaming content over network via USB/Ethernet adapter. A user/program could use this flaw to crash the kernel, resulting in DoS.
