Linux Kernel DataImage SCF0700C48GGU18 Panel Connector Type Missing Vulnerability

A vulnerability exists in the Linux kernel's handling of the DataImage SCF0700C48GGU18 panel within the DRM subsystem. The issue arises because the connector type for this panel is not specified, leading to a warning and a backtrace in the kernel log. As a result, the panel fails to function properly. The warning is triggered by a check for a valid connector type in the 'devm_drm_panel_bridge_add()' function. When the connector type is absent, the function cannot add the panel, causing operational issues.

Impact

The missing connector type prevents the DataImage SCF0700C48GGU18 panel from functioning correctly, causing it not to be recognized or used by the system.

Reproduction

The vulnerability can be reproduced by attempting to use the DataImage SCF0700C48GGU18 panel without a specified connector type. This will result in a warning being logged, indicating that the panel could not be added due to the absence of a valid connector type.

Remediation

The vulnerability has been addressed by adding the missing connector type to the panel's description in the Linux kernel source code. Users should update to the latest version of the Linux kernel where this fix has been applied.
