In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: clamp maximum hashtable size to INT_MAX Use INT_MAX as maximum size for the conntrack hashtable. Otherwise, it is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when resizing hashtable because __GFP_NOWARN is unset. See: 0708a0afe291 ("mm: Consider __GFP_NOWARN flag for oversized kvmalloc() calls") Note: hashtable resize is only possible from init_netns.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: conntrack: fijar el tamaño máximo de la tabla hash a INT_MAX Utilice INT_MAX como tamaño máximo para la tabla hash de conntrack. De lo contrario, es posible alcanzar WARN_ON_ONCE en __kvmalloc_node_noprof() al cambiar el tamaño de la tabla hash porque __GFP_NOWARN no está configurado. Consulte: 0708a0afe291 ("mm: Considere el indicador __GFP_NOWARN para llamadas kvmalloc() de gran tamaño") Nota: el cambio de tamaño de la tabla hash solo es posible desde init_netns.
