(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."}, {"lang": "es", "value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nusb: renesas_usbhs: correcci\u00f3n de uso despu\u00e9s de liberaci\u00f3n en la ISR durante la eliminaci\u00f3n del dispositivo\n\nEn usbhs_remove(), el controlador libera recursos (incluyendo el array de pipes) mientras el gestor de interrupciones (usbhs_interrupt) todav\u00eda est\u00e1 registrado.
