In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_pipapo: clamp maximum map bucket size to INT_MAX Otherwise, it is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when resizing hashtable because __GFP_NOWARN is unset. Similar to: b541ba7d1f5a ("netfilter: conntrack: clamp maximum hashtable size to INT_MAX")
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nft_set_pipapo: fijar el tamaño máximo del contenedor de mapas a INT_MAX. De lo contrario, es posible que se active WARN_ON_ONCE en __kvmalloc_node_noprof() al redimensionar la tabla hash porque __GFP_NOWARN no está configurado. Similar a: b541ba7d1f5a ("netfilter: conntrack: fijar el tamaño máximo de la tabla hash a INT_MAX")
