CVE-2017-5548 (CCN-121664)

Assigned:2017-02-06
Published:2017-02-06
Updated:2019-10-03
Summary:drivers/net/ieee802154/atusb.c in the Linux kernel 4.9.x before 4.9.6 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.
