"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: dwc2: gadget: Fix spin_lock/unlock mismatch in dwc2_hsotg_udc_stop()\n\ndwc2_gadget_exit_clock_gating() internally calls call_gadget() macro,\nwhich expects hsotg->lock to be held since it does spin_unlock/spin_lock\naround the gadget driver callback invocation.\n\nHowever, dwc2_hsotg_udc_stop() calls dwc2_gadget_exit_clock_gating()\nwithout holding the lock. This leads to:\n - spin_unlock on a lock that is not held (undefined behavior)\n - The lock remaining held after dwc2_gadget_exit_clock_gating() returns,\n causing a deadlock when spin_lock_irqsave() is called later in the\n same function.\n\nFix this by acquiring hsotg->lock before calling\ndwc2_gadget_exit_clock_gating() and releasing it afterwards, which\nsatisfies the locking requirement of the call_gadget() macro."
