In the Linux kernel, the following vulnerability has been resolved:netfilter: conntrack: clamp maximum hashtable size to INT_MAXUse 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.
