Description Adam Mariš 2017-04-25 09:45:48 EDT 
drivers/media/usb/dvb-usb/dvb-usb-firmware.c in the Linux kernel 4.9.x
and 4.10.x before 4.10.7 interacts incorrectly with the
CONFIG_VMAP_STACK option, which allows local users to cause a denial
of service (system crash or memory corruption) or possibly have
unspecified other impact by leveraging use of more than one virtual
page for a DMA scatterlist.
