CVE-2026-43300

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/panel: Fix a possible null-pointer dereference in jdi_panel_dsi_remove()<br /> <br /> In jdi_panel_dsi_remove(), jdi is explicitly checked, indicating that it<br /> may be NULL:<br /> <br /> if (!jdi)<br /> mipi_dsi_detach(dsi);<br /> <br /> However, when jdi is NULL, the function does not return and continues by<br /> calling jdi_panel_disable():<br /> <br /> err = jdi_panel_disable(&amp;jdi-&gt;base);<br /> <br /> Inside jdi_panel_disable(), jdi is dereferenced unconditionally, which can<br /> lead to a NULL-pointer dereference:<br /> <br /> struct jdi_panel *jdi = to_panel_jdi(panel);<br /> backlight_disable(jdi-&gt;backlight);<br /> <br /> To prevent such a potential NULL-pointer dereference, return early from<br /> jdi_panel_dsi_remove() when jdi is NULL.
