CVE-2026-80658

Kernel fault via uninitialized driver data dereference

Published Aug 28, 2026 · Updated Aug 28, 2026

NULL pointer dereference in Linux 6.18 allows attackers to trigger a kernel fault during Rockchip DisplayPort driver removal. The dw_dp_remove() callback passes dp->dev to component_del() after platform_get_drvdata() returns NULL because the bind callback never initialized the driver data. The path requires an earlier Rockchip DRM bind failure followed by removal of the RK3588 DPTX platform driver; no remote trigger is published.
