CVE-2017-8069 (CCN-125358)

Assigned:2017-04-16
Published:2017-04-16
Updated:2017-04-27
Summary:drivers/net/usb/rtl8150.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.
