  "title": "usb: phy: fsl-usb: Fix use-after-free in delayed work during device removal",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: phy: fsl-usb: Fix use-after-free in delayed work during device removal  The delayed work item otg_event is initialized in fsl_otg_conf() and scheduled under two conditions: 1. When a host controller binds to the OTG controller. 2. When the USB ID pin state changes (cable insertion/removal).  A race condition occurs when the device is removed via fsl_otg_remove(): the fsl_otg instance may be freed while the delayed work is still pending or executing. This leads to use-after-free when the work function fsl_otg_event() accesses the already freed memory.  The problematic scenario:  (detach thread)            | (delayed work) fsl_otg_remove()           |   kfree(fsl_otg_dev) //FREE| fsl_otg_event()                            |   og = container_of(...) //USE                            |   og-\u003E //USE  Fix this by calling disable_delayed_work_sync() in fsl_otg_remove() before deallocating the fsl_otg structure. This ensures the delayed work is properly canceled and completes execution prior to memory deallocation.  This bug was identified through static analysis.",
