CVE-2026-72346

Suspend interruption via uninitialized profile device

Published Aug 15, 2026 · Updated Aug 15, 2026

NULL pointer dereference in Linux 7.1 bitland-mifs-wmi allows local users to halt suspend by suspending a system with its event device. The event-device probe returns before initializing data->pp_dev, but bitland_mifs_wmi_suspend() still passes that NULL pointer to laptop_profile_get(). The flaw requires the Bitland event WMI device and a local user able to initiate suspend; the resulting kernel Oops stops the suspend sequence.
