Description Marcus Meissner 2017-04-24 11:04:09 UTC

CVE-2017-8063

drivers/media/usb/dvb-usb/cxusb.c in the Linux kernel 4.9.x and 4.10.x before
4.10.12 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows
local users to cause a denial of service (system crash) or possibly have
unspecified other impact by leveraging use of more than one virtual page for a
DMA scatterlist.

Comment 1 Marcus Meissner 2017-04-24 11:05:39 UTC

its been there for a while

Comment 2 Takashi Iwai 2017-04-24 14:12:06 UTC

CONFIG_VMAP_STACK is new in 4.9, and it's already fixed in the recent 4.10.x.
We are unaffected.
