CVE-2026-43300

Local kernel crash via NULL panel dereference

Published May 8, 2026 · Updated May 8, 2026

NULL pointer dereference in the Linux Kernel JDI panel driver allows local users to crash the kernel during device removal. The jdi_panel_dsi_remove() path detects a NULL jdi pointer but continues into jdi_panel_disable(), which unconditionally dereferences it to disable the backlight. Exploitation requires low-privileged local access and reachability of the JDI panel removal path; the documented consequence is an availability-only kernel crash.
