CVE-2023-53784

A vulnerability was found in the Linux kernel's DRM subsystem, specifically within the DW HDMI bridge driver .A prior commit intended to improve SCDC (Source Connection Description Channel) debugging changed the interface to retrieve an I2C adapter from a connector structure. However, in the dw_hdmi implementation, the wrong connector pointer was inadvertently used to access the I2C adapter information. This incorrect usage, particularly when the Digital Visual Interface or DisplayPort connector was not properly initialized via the bridge attachment callback, resulting in a NULL pointer dereference.
