GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2017-8063

Vulnerability from fkie_nvd - Published: 2017-04-23 05:59 - Updated: 2026-06-17 01:25
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
drivers/media/usb/dvb-usb/cxusb.c in the Linux kernel 4.9.x and 4.10.x before 4.10.12 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.
