CVE-2025-38507

Kernel stall or panic via Bluetooth resume

Published Aug 16, 2025 · Updated May 11, 2026

Denial of service in Linux kernel 5.16 through affected 6.x branches allows local users to stall or panic the kernel during resume. The nintendo_hid_suspend path fails to mark the controller suspended, while nintendo_hid_resume calls joycon_init after Bluetooth connectivity is lost, causing waits for input reports. A Bluetooth-connected Nintendo controller and a suspend/resume cycle are required; unreliable or lost connectivity can hang or panic the host.
