CVE-2024-56719

CVE-2024-56719 affects the Linux kernel net driver stmmac (TSO DMA path). The root cause was unbalanced DMA map/unmap: tx_skbuff_dma[] was populated later in stmmac_tso_xmit(), causing the dma cookie used by dma_unmap_single() to differ from dma_map_single() when priv->dma_cap.addr64 > 32. ...

CVE-2025-39770
