  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: dwc2: gadget: Fix spin_lock/unlock mismatch in dwc2_hsotg_udc_stop()  dwc2_gadget_exit_clock_gating() internally calls call_gadget() macro, which expects hsotg-\u003elock to be held since it does spin_unlock/spin_lock around the gadget driver callback invocation.  However, dwc2_hsotg_udc_stop() calls dwc2_gadget_exit_clock_gating() without holding the lock. This leads to:  - spin_unlock on a lock that is not held (undefined behavior)  - The lock remaining held after dwc2_gadget_exit_clock_gating() returns,    causing a deadlock when spin_lock_irqsave() is called later in the    same function.  Fix this by acquiring hsotg-\u003elock before calling dwc2_gadget_exit_clock_gating() and releasing it afterwards, which satisfies the locking requirement of the call_gadget() macro.",
