CVE-2025-21788

Summary (CVE-2025-21788) : In the Linux kernel’s net/ethernet/ti/am65-cpsw driver, memory allocated for SKB via am65_cpsw_build_skb() may leak when an XDP program does not return XDP_PASS. The root cause is allocating SKB memory before evaluating the XDP program result, which wastes CPU cycles fo...
