CVE-2017-5547: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

drivers/hid/hid-corsair.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.

Affected products

• Linux Linux Kernel: from 4.4, before 4.4.45 (fixed in 4.4.45); from 4.5, before 4.9.6 (fixed in 4.9.6)
