"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwatchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger\n\nWhen the cpu5wdt module is removing, the origin code uses del_timer() to\nde-activate the timer. If the timer handler is running, del_timer() could\nnot stop it and will return directly. If the port region is released by\nrelease_region() and then the timer handler cpu5wdt_trigger() calls outb()\nto write into the region that is released, the use-after-free bug will\nhappen.\n\nChange del_timer() to timer_shutdown_sync() in order that the timer handler\ncould be finished before the port region is released."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: watchdog: cpu5wdt.c: corrige el error de use-after-free causado por cpu5wdt_trigger Cuando se elimina el m\u00f3dulo cpu5wdt, el c\u00f3digo de origen usa del_timer() para desactivar el temporizador. Si el controlador del temporizador se est\u00e1 ejecutando, del_timer() no pudo detenerlo y regresar\u00e1 directamente. Si la regi\u00f3n del puerto es liberada por release_region() y luego el controlador del temporizador cpu5wdt_trigger() llama a outb() para escribir en la regi\u00f3n que se libera, se producir\u00e1 el error de use-after-free. Cambie del_timer() a timer_shutdown_sync() para que el controlador del temporizador pueda finalizar antes de que se libere la regi\u00f3n del puerto."
