CVE-2026-23049

Display outage via missing connector type

Published Feb 4, 2026 · Updated Feb 4, 2026

Availability failure in affected Linux Kernel releases allows local users to prevent a DataImage SCF0700C48GGU18 panel from operating. The panel-simple descriptor omits its connector_type, so devm_drm_panel_bridge_add() rejects the invalid type and does not add the panel bridge. The defect is reached when the system probes that specific panel, producing a kernel warning and leaving the display unavailable without affecting data confidentiality or integrity.
