CVE-2026-72251
CVE-2026-72251 concerns the Linux kernel netfilter nf_nat_sip path. The issue is a memory-pointer/buffer handling flaw: if skb_ensure_writable() reallocates a cloned/fragmented skb, nf_nat_sip() may not update the destination pointer (dptr ) to the new buffer, risking a stale data pointer and pot...
