Description Prasad Pandit 2014-09-13 01:21:55 UTC

Linux kernel built with the USB Serial Converter support(USB_SERIAL) along with
a USB ConnectTech WhiteHEAT Serial Driver(CONFIG_USB_SERIAL_WHITEHEAT) is
vulnerable to a memory corruption flaw. It could occur when reading completion
commands via USB Request Blocks buffers.

A local user with physical access to the system could use this flaw to corrupt
kernel memory area or crash the system kernel resulting in DoS.
