CVE-2026-43170

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: gadget: Move vbus draw to workqueue context Currently dwc3_gadget_vbus_draw() can be called from atomic context, which in turn invokes power-supply-core APIs. And some these PMIC APIs have operations that may sleep, leading to kernel panic. Fix this by moving the vbus_draw into a workqueue context.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: usb: dwc3: gadget: Mover el consumo de vbus al contexto de workqueue Actualmente, se puede llamar a dwc3_gadget_vbus_draw() desde un contexto atómico, lo que a su vez invoca las API de power-supply-core. Y algunas de estas API de PMIC tienen operaciones que pueden suspenderse, lo que lleva a un pánico del kernel. Solucione esto moviendo el consumo de vbus a un contexto de workqueue.
