What is CVE-2015-8816?

The hub_activate function within the Linux kernel, prior to version 4.3.5, is vulnerable due to improper management of hub-interface data structures. This flaw allows attackers located in close physical proximity to exploit the vulnerability by unplugging a USB hub device. Such action can lead to invalid memory access, resulting in potential system crashes and denial of service. This vulnerability underscores the importance of maintaining robust security measures for USB interfaces in Linux-based systems.
