CVE-2017-8070

drivers/net/usb/catc.c in the Linux kernel 4.9.x before 4.9.11 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 09:31:08 UTC

(all kernels affected. catc driver is supported in SLE)

Comment 2 Michal Kubeček 2017-04-24 12:55:18 UTC

CONFIG_VMAP_STACK is only available since v4.9-rc1. As the fix is in v4.10-rc8
and TW is already on 4.10.x, it seems that none of our kernels needs fixing.

Reassigned back to security team.  Feel free to close.

Comment 4 Marcus Meissner 2017-04-28 11:20:52 UTC

fixed upstream, no current SUSE or openSUSE affected
