Description Marcus Meissner 2017-04-24 09:47:02 UTC

CVE-2017-8067

drivers/char/virtio_console.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 09:50:25 UTC

2.6.24 introduced this driver. supported in SLE

Comment 2 Takashi Iwai 2017-04-24 14:10:12 UTC

CONFIG_VMAP_STACK is new in 4.9, and it's already fixed in 4.10.12, thus TW is OK.
We are unaffected.

Comment 3 Takashi Iwai 2017-04-28 09:13:31 UTC

Reassigned back to security team.  Feel free to close.

Comment 4 Marcus Meissner 2017-04-28 11:25:35 UTC

fixed upstream, no current SUSE or openSUSE affected
