Unknown Unknown - Not Provided
Missing Connector Type Causes Kernel Warning in DataImage Panel

Publication date: 2026-02-04

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panel The connector type for the DataImage SCF0700C48GGU18 panel is missing and devm_drm_panel_bridge_add() requires connector type to be set. This leads to a warning and a backtrace in the kernel log and panel does not work: " WARNING: CPU: 3 PID: 38 at drivers/gpu/drm/bridge/panel.c:379 devm_drm_of_get_bridge+0xac/0xb8 " The warning is triggered by a check for valid connector type in devm_drm_panel_bridge_add(). If there is no valid connector type set for a panel, the warning is printed and panel is not added. Fill in the missing connector type to fix the warning and make the panel operational once again.

Executive Summary

This vulnerability occurs in the Linux kernel related to the DataImage SCF0700C48GGU18 panel. The issue is that the connector type for this panel was missing, but the function devm_drm_panel_bridge_add() requires a valid connector type to be set.

Because the connector type was not set, the kernel triggers a warning and a backtrace in the kernel log, and as a result, the panel does not work properly.

The fix involves filling in the missing connector type to prevent the warning and make the panel operational again.

Impact Analysis

This vulnerability can cause the DataImage SCF0700C48GGU18 panel to fail to operate because the missing connector type triggers a kernel warning and prevents the panel from being added properly.

Users may see warnings and backtraces in the kernel log, and the affected panel will not function until the connector type is correctly set.

Compliance Impact

Detection Guidance

This vulnerability can be detected by checking the kernel logs for specific warning messages related to the DataImage SCF0700C48GGU18 panel connector type.

  • Use the command 'dmesg | grep -i "WARNING: CPU"' to search for warnings in the kernel log.
  • Specifically look for messages containing 'devm_drm_of_get_bridge' or references to 'panel.c' and 'connector type'.
  • Presence of such warnings indicates the missing connector type issue described in the vulnerability.
Mitigation Strategies

The immediate mitigation is to update the Linux kernel to a version where the connector type for the DataImage SCF0700C48GGU18 panel is properly set.

This fix prevents the warning and backtrace in the kernel log and restores proper panel operation.

Until the update is applied, monitoring kernel logs for the warning can help identify affected systems.
