In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: clamp maximum hashtable size to INTMAX Use INTMAX as maximum size for the conntrack hashtable. Otherwise, it is possible to hit WARNONONCE in _kvmallocnodenoprof() when resizing hashtable because _GFPNOWARN is unset. See: 0708a0afe291 ("mm: Consider _GFPNOWARN flag for oversized kvmalloc() calls") Note: hashtable resize is only possible from initnetns.
