"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: kunit: corrige la fuga del recuento de referencias en kfree_at_end El problema del recuento de referencias ocurre en la ruta normal de kfree_at_end(). Cuando se invoca kunit_alloc_and_get_resource(), la funci\u00f3n se olvida de manejar el objeto de recurso devuelto, cuyo recuento aument\u00f3 en el interior, lo que provoca una fuga de recuento. Solucione este problema llamando a kunit_alloc_resource() en lugar de kunit_alloc_and_get_resource(). Se corrigi\u00f3 lo siguiente al aplicar: Shuah Khan VERIFICAR: La alineaci\u00f3n debe coincidir con el par\u00e9ntesis abierto + kunit_alloc_resource(test, NULL, kfree_res_free, GFP_KERNEL, (void *)to_free);"
