Description Adam Mariš 2017-04-25 13:43:02 UTC
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.
