  "summary": "usb: renesas_usbhs: fix use-after-free in ISR during device removal",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: renesas_usbhs: fix use-after-free in ISR during device removal\n\nIn usbhs_remove(), the driver frees resources (including the pipe array)\nwhile the interrupt handler (usbhs_interrupt) is still registered. If an\ninterrupt fires after usbhs_pipe_remove() but before the driver is fully\nunbound, the ISR may access freed memory, causing a use-after-free.\n\nFix this by calling devm_free_irq() before freeing resources. This ensures\nthe interrupt handler is both disabled and synchronized (waits for any\nrunning ISR to complete) before usbhs_pipe_remove() is called.",
