CVE-2026-43300

Estado: AnalizadaMedia (5.5)—

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:

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

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

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

  if (!jdi)

  err = jdi_panel_disable(&jdi->base);

  struct jdi_panel *jdi = to_panel_jdi(panel);
  backlight_disable(jdi->backlight);
