Title
drm/panel: Fix a possible null-pointer dereference in jdi_panel_dsi_remove()
Summary
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.
Severity ?
