CVE-2017-5547 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
