Overview

CVE-2026-43300 is a medium-severity vulnerability. It was published on May 8, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
