  "details" : [ "A flaw was found in the Linux kernel's USB DWC3 gadget driver. This vulnerability occurs when the `dwc3_gadget_vbus_draw()` function is called from an atomic context, which then invokes power management integrated circuit (PMIC) APIs that may cause the system to sleep. An attacker could exploit this condition to trigger a kernel panic, leading to a Denial of Service (DoS) on the affected system." ],
