Background
The Kernel package is a fundamental component of the Linux operating system. It provides the core functionality and interfaces for communication between hardware and software components. The cfg80211 module within the Kernel package is responsible for managing wireless network configuration. It allows users to connect to and interact with wireless networks. However, a vulnerability has been identified in the cfg80211 module that can be exploited when switching away from OCB (Outside Context of a BSS) mode.
Vulnerability Detail
The vulnerability in the cfg80211 module occurs when switching away from OCB mode. OCB mode is used for wireless communication in scenarios where traditional infrastructure-based networks are not available. The vulnerability allows an attacker to perform unauthorized actions or gain elevated privileges when transitioning from OCB mode to another mode. The impact of this vulnerability can range from unauthorized access to sensitive information to complete system compromise. The vulnerability has been fixed in Linux Kernel version v5.12.14 by commit c84ccd00b25521f349ceca3f0b36b2410635c225.
