What it is

In the Linux kernel, the following vulnerability has been resolved:

drm/bridge: it6505: Initialize AUX channel in it6505_i2c_probe

During device boot, the HPD interrupt could be triggered before the DRM

subsystem registers it6505 as a DRM bridge. In such cases, the driver

tries to access AUX channel and causes NULL pointer dereference.

Initializing the AUX channel earlier to prevent such error.
