Background
The PM: domains package is a component of the Linux Kernel that manages power domains. Power domains are groups of devices that can be powered on or off together to conserve energy. The PM: domains package provides functionality for managing the power state of these domains. It is an essential part of the Linux Kernel and is used by various device drivers and subsystems.
Vulnerability Detail
The sleep-in-atomic bug in the PM: domains package is caused by the genpd_debug_remove() function. This bug can lead to sleep operations being performed in atomic context, which is not allowed and can result in undefined behavior. An attacker may be able to exploit this vulnerability to cause a denial of service or potentially execute arbitrary code with elevated privileges. The bug was introduced in version v5.11 of the Linux Kernel and has been fixed in version v5.16.19.
