Description Adam Mariš 2017-04-25 13:48:07 UTC
drivers/net/can/usb/gs_usb.c in the Linux kernel 4.9.x and 4.10.x
before 4.10.2 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.
