CVE-2026-43300

In the Linux kernel, the following vulnerability has been resolved:

drm/panel: Fix a possible null-pointer dereference in jdipaneldsi_remove()

In jdipaneldsi_remove(), jdi is explicitly checked, indicating that it may be NULL:

if (!jdi) mipidsidetach(dsi);

However, when jdi is NULL, the function does not return and continues by calling jdipaneldisable():

err = jdipaneldisable(&jdi->base);

Inside jdipaneldisable(), jdi is dereferenced unconditionally, which can lead to a NULL-pointer dereference:

struct jdipanel *jdi = topaneljdi(panel); backlightdisable(jdi->backlight);

To prevent such a potential NULL-pointer dereference, return early from jdipaneldsi_remove() when jdi is NULL.
