CVE-2024-46698

System crash via stale sysfb resource dereference

Published Sep 13, 2024 · Updated May 23, 2026

NULL pointer dereference in affected Linux kernels allows local users to crash systems during conflicting GPU aperture removal. During aperture_remove_conflicting_pci_devices(), a non-VGA boot display releases sysfb resources without disabling sysfb, and a later VGA GPU makes sysfb_disable() dereference those freed resources. Reachability requires the non-VGA device to be the boot display, a second VGA-class GPU, and the documented probe order; the bounded consequence is a kernel crash.
