CVE-2026-31649

The CVE-2026-31649 issue affects the Linux kernel’s stmmac driver, where jumbo_frm() can underflow when processing fragmented packets. If nopaged_len is small but skb->len is large, len = nopaged_len - buf_len (with buf_len clamped to min(nopaged_len, bmax)) can still yield a large unsigned va...
