Name of the Vulnerable Software and Affected Versions
Linux Kernel (affected versions not specified)
Description
A vulnerability was found in the HCI sockets implementation due to a missing capability check in the Linux Kernel. This flaw allows an attacker to execute management commands without authorization, compromising the confidentiality, integrity, and availability of Bluetooth communication. The issue is related to insufficient permission checks when handling ioctl system calls of HCI sockets, enabling tasks without the proper CAP NET ADMIN capability to mark HCI sockets as trusted. As a result, unprivileged users can acquire a trusted socket, leading to unauthorized execution of management commands. If successfully exploited, the vulnerability can be used to pair the controller with malicious devices, even if the Bluetooth service is disabled or not installed.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
