Title
drm/bridge: it6505: Initialize AUX channel in it6505_i2c_probe
Summary
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.
Severity ?
No CVSS data available.
