CVE-2026-43300 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/panel: Fix a possible null-pointer dereference in jdi_panel_dsi_remove() In jdi_panel_dsi_remove(), jdi is explicitly checked, indicating that it may be NULL: if (!jdi) mipi_dsi_detach(dsi); However, when jdi is NULL, the function does not return and continues by calling jdi_panel_disable(): err = jdi_panel_disable(&jdi->base); Inside jdi_panel_disable(), jdi is dereferenced unconditionally, which can lead to a NULL-pointer dereference: struct jdi_panel *jdi = to_panel_jdi(panel); backlight_disable(jdi->backlight); To prevent such a potential NULL-pointer dereference, return early from jdi_panel_dsi_remove() when jdi is NULL.
A null pointer dereference vulnerability has been identified in the Linux kernel's handling of certain display panels. Specifically, in the function 'jdi_panel_dsi_remove()', there is a check for a 'jdi' pointer that may be NULL. If 'jdi' is NULL, the function detaches the MIPI DSI device but does not return, instead proceeding to disable the panel by calling 'jdi_panel_disable()'. This latter function unconditionally dereferences 'jdi', leading to a potential null pointer dereference. The vulnerability has been addressed by modifying 'jdi_panel_dsi_remove()' to return early when 'jdi' is NULL, preventing the unsafe dereference.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the official Linux kernel website.
