Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains an issue where logging was performed using DRM functions before the bridge was attached, potentially leading to NULL pointer kernel panics during AUX transfers. The logging has been changed to use
dev {err,info}() in the mtk dp aux transfer() and mtk dp aux do transfer() functions to avoid these panics. This issue may occur when AUX transfers are triggered from the panel driver before the MediaTek DisplayPort (MTK-DP) bridge is attached, particularly in preparation for AUX-bus support.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
