Linux · Linux Kernel · CVE-2015-8816
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions prior to 4.3.5
**Description**
The issue is related to the `hub activate` function in the Linux kernel, which does not properly maintain a hub-interface data structure. This allows physically proximate attackers to cause a denial of service, resulting in invalid memory access and a system crash, or possibly have other unspecified impacts by unplugging a USB hub device.
**Recommendations**
For Linux kernel versions prior to 4.3.5, update to version 4.3.5 or later to resolve the issue. As a temporary workaround, consider restricting access to USB hub devices to minimize the risk of exploitation.
