Description Marcus Meissner 2017-04-24 10:49:13 UTC

drivers/media/usb/dvb-usb-v2/dvb_usb_core.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 memory
corruption) 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 11:03:45 UTC
"struct device device" seems to be there for some time
Comment 2 Takashi Iwai 2017-04-24 14:12:16 UTC
CONFIG_VMAP_STACK is new in 4.9, and it's already fixed in the recent 4.10.x.
We are unaffected.
Comment 3 Takashi Iwai 2017-04-28 09:12:32 UTC
Reassigned back to security team.  Feel free to close.
Comment 4 Marcus Meissner 2017-04-28 11:26:32 UTC
fixed upstream, no current SUSE or openSUSE affected
