Background

The ath10k driver is a component of the Linux Kernel that provides support for Qualcomm Atheros 802.11ac wireless LAN (WLAN) devices. It enables communication between the operating system and the WLAN hardware, allowing users to connect to wireless networks. The driver is responsible for managing various aspects of the WLAN functionality, including device initialization, firmware loading, and data transmission. However, a vulnerability has been discovered in the ath10k driver that affects its behavior during the suspend process when the driver state is set to RESTARTING.

Vulnerability Detail

The vulnerability in the ath10k driver occurs when the driver is in the RESTARTING state during the suspend process. In this state, the driver should skip the ath10k_halt function, which is responsible for halting the WLAN device. However, due to a coding error, the ath10k_halt function is not skipped, leading to potential issues during the suspend process. The impact of this vulnerability is not yet proven, but it could potentially result in the WLAN device not being properly halted during suspend, leading to unexpected behavior or system instability. The vulnerability has been fixed in Linux Kernel version v5.15.46 by commit c2272428090d0d215a3f017cbbbad731c07eee53.
