Description Marcus Meissner 2017-04-24 11:14:37 UTC
CVE-2017-8061

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.

Comment 1 Takashi Iwai 2017-04-24 14:11:47 UTC
CONFIG_VMAP_STACK is new in 4.9, and it's already fixed in the recent 4.10.x.
We are unaffected.

Reassigned back to security team.  Feel free to close.
Comment 3 Marcus Meissner 2017-04-28 11:16:16 UTC
This does not affect current SUSE or openSUSE products.
