CVE-2009-3238

The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time."

La función get_random_int de drivers/char/random.c en el kernel de Linux anterior a v2.6.30, produce números que nos son suficientemente aleatorios, esto permite a los atacantes predecir el valor devuelto y permite que se puedan superar los mecanismos de protección basados en la aleatoriedad, a través de vectores que eleven la tendencia de la función a "devolver el mismo valor una y otra vez durante largos periodos de tiempo".
