UBUNTU-CVE-2026-43300: Medium severity ubuntu/linux-hwe-edge vulnerability

Published May 8, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: drm/panel: Fix a possible null-pointer dereference in jdipaneldsiremove() In jdipaneldsiremove(), 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 jdipaneldsiremove() when jdi is NULL.
