Background
The mac80211 package is a component of the Linux Kernel that provides the implementation of the IEEE 802.11 wireless networking stack. It is responsible for managing wireless network interfaces and handling various operations such as scanning, authentication, and data transmission. The package is widely used in Linux-based systems and is crucial for enabling wireless connectivity. However, a vulnerability has been discovered in the mac80211 package that could lead to a potential double free issue when joining a mesh network.
Vulnerability Detail
