"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nf_tables: corrige memleak cuando caducan m\u00e1s de 255 elementos Cuando caducan m\u00e1s de 255 elementos, se supone que debemos cambiar a una nueva estructura de contenedor gc. Esto nunca sucede: el tipo u8 se ajustar\u00e1 antes de alcanzar el l\u00edmite y nft_trans_gc_space() siempre devuelve verdadero. Esto significa que reciclamos la estructura inicial del contenedor gc y perdemos la pista de los elementos anteriores. Mientras lo hace, no elimine 'gc' despu\u00e9s de que lo hayamos pasado a call_rcu."
