CVE-2025-21648

CVE-2025-21648 affects the Linux kernel netfilter conntrack code. The vulnerability arises from the hashtable resize path where the maximum size could exceed practical limits, risking a WARN_ON_ONCE in __kvmalloc_node_noprof() when __GFP_NOWARN is unset. The fix clamps the conntrack hashtable siz...
