CVE-2024-46799Network attack vector

Gateway crash via nonexistent XDP TX channel

Published Sep 18, 2024 · Updated Aug 5, 2026

NULL pointer dereference in Linux kernel 6.10 through 6.10.9 allows remote attackers to crash systems via network traffic. The am65_cpsw_ndo_xdp_xmit function selects a transmit channel from the maximum queue count instead of the actual count, so it can dereference a missing channel. The path requires a TI AM65 CPSW interface configured for XDP forwarding with one TX queue; received traffic can then interrupt the system.
