CVE-2025-38507

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

HID: nintendo: avoid bluetooth suspend/resume stalls

Ensure we don't stall or panic the kernel when using bluetooth-connected controllers. This was reported as an issue on android devices using kernel 6.6 due to the resume hook which had been added for usb joycons.

First, set a new state value to JOYCON_CTLR_STATE_SUSPENDED in a newly-added nintendo_hid_suspend. This makes sure we will not stall out the kernel waiting for input reports during led classdev suspend. The stalls could happen if connectivity is unreliable or lost to the controller prior to suspend.

Second, since we lose connectivity during suspend, do not try joycon_init() for bluetooth controllers in the nintendo_hid_resume path.

Tested via multiple suspend/resume flows when using the controller both in USB and bluetooth modes.

Esto se informó como un problema en dispositivos Android que usan el kernel 6.6 debido al gancho de reanudación que se había agregado para los joycons usb. Primero, establezca un nuevo valor de estado en JOYCON_CTLR_STATE_SUSPENDED en un nintendo_hid_suspend recién agregado. Esto asegura que no bloquearemos el kernel esperando informes de entrada durante la suspensión de classdev led. Los bloqueos podrían ocurrir si la conectividad no es confiable o se pierde con el controlador antes de la suspensión. Segundo, dado que perdemos la conectividad durante la suspensión, no intentes joycon_init() para controladores bluetooth en la ruta nintendo_hid_resume. Probado a través de múltiples flujos de suspensión/reinicio al usar el controlador en modo USB y bluetooth."
