Background
The phonet/pep package is a component of the Linux Kernel, which is responsible for handling the Phonet protocol and its associated protocols. Phonet is a network protocol used for communication between devices in embedded systems. The phonet/pep package provides the necessary functionality to enable and manage Phonet pipes, which are used for data transfer between devices. However, a vulnerability has been discovered in the package that allows the enabling of an unbound pipe.
Vulnerability Detail
The vulnerability in the phonet/pep package allows the enabling of an unbound pipe. An unbound pipe refers to a pipe that has not been properly initialized or associated with any specific device or endpoint. By enabling an unbound pipe, an attacker could potentially exploit this vulnerability to perform unauthorized data transfer or disrupt the normal operation of the system. The impact and attack plausibility of this vulnerability have not yet been proven. The vulnerability has been fixed in Linux Kernel version v5.4.169 by commit 48c76fc53582e7f13c1e0b11c916e503256c4d0b.
