"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmisc: fastrpc: Fix use-after-free and race in fastrpc_map_find\n\nCurrently, there is a race window between the point when the mutex is\nunlocked in fastrpc_map_lookup and the reference count increasing\n(fastrpc_map_get) in fastrpc_map_find, which can also lead to\nuse-after-free.\n\nSo lets merge fastrpc_map_find into fastrpc_map_lookup which allows us\nto both protect the maps list by also taking the &fl->lock spinlock and\nthe reference count, since the spinlock will be released only after.\nAdd take_ref argument to make this suitable for all callers."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: misc: fastrpc: corrige use-after-free y ejecuci\u00f3n en fastrpc_map_find Actualmente, hay una ventana de ejecuci\u00f3n entre el punto en el que se desbloquea el mutex en fastrpc_map_lookup y el recuento de referencias aumenta (fastrpc_map_get ) en fastrpc_map_find, lo que tambi\u00e9n puede generar use-after-free. Entonces, fusionemos fastrpc_map_find con fastrpc_map_lookup, lo que nos permite proteger la lista de mapas tomando tambi\u00e9n el &fl->lock spinlock y el recuento de referencias, ya que el spinlock se liberar\u00e1 solo despu\u00e9s. Agregue el argumento take_ref para que sea adecuado para todas las personas que llaman."
