Last modified
CVE-2015-8816 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device.. EPSS estimates a 0.54% chance of exploitation in the next 30 days.
