CVE-2026-98571Hinoki check available

Unspecified impact via stale RX-page pointer

Published Oct 18, 2026 · Updated Oct 18, 2026

Stale-page reuse in Linux 6.14 stmmac allows attackers unspecified impact via the receive path after socket-buffer allocation fails. In stmmac_rx(), failed napi_build_skb() leaves buf->page referencing a recycled page, so stmmac_rx_refill() skips allocation and reuses that page in an RX descriptor. The path requires an active stmmac interface and allocation failure; attacker control, required privileges, and consequences beyond incorrect page reuse are not established.
