CVE-2025-21629 (GCVE-0-2025-21629)

Vulnerability from cvelistv5 – Published: 2025-01-15 13:06 – Updated: 2026-08-05 11:53

Title

net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets

Summary

In the Linux kernel, the following vulnerability has been resolved: net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets The blamed commit disabled hardware offoad of IPv6 packets with extension headers on devices that advertise NETIF_F_IPV6_CSUM, based on the definition of that feature in skbuff.h: * * - %NETIF_F_IPV6_CSUM * - Driver (device) is only able to checksum plain * TCP or UDP packets over IPv6. These are specifically * unencapsulated packets of the form IPv6|TCP or * IPv6|UDP where the Next Header field in the IPv6 * header is either TCP or UDP. IPv6 extension headers * are not supported with this feature. This feature * cannot be set in features for a device with * NETIF_F_HW_CSUM also set. This feature is being * DEPRECATED (see below). The change causes skb_warn_bad_offload to fire for BIG TCP packets. [ 496.310233] WARNING: CPU: 13 PID: 23472 at net/core/dev.c:3129 skb_warn_bad_offload+0xc4/0xe0 [ 496.310297] ? skb_warn_bad_offload+0xc4/0xe0 [ 496.310300] skb_checksum_help+0x129/0x1f0 [ 496.310303] skb_csum_hwoffload_help+0x150/0x1b0 [ 496.310306] validate_xmit_skb+0x159/0x270 [ 496.310309] validate_xmit_skb_list+0x41/0x70 [ 496.310312] sch_direct_xmit+0x5c/0x250 [ 496.310317] __qdisc_run+0x388/0x620 BIG TCP introduced an IPV6_TLV_JUMBO IPv6 extension header to communicate packet length, as this is an IPv6 jumbogram. But, the feature is only enabled on devices that support BIG TCP TSO. The header is only present for PF_PACKET taps like tcpdump, and not transmitted by physical devices. For this specific case of extension headers that are not transmitted, return to the situation before the blamed commit and support hardware offload. ipv6_has_hopopt_jumbo() tests not only whether this header is present, but also that it is the only extension header before a terminal (L4) header.

IPv6 extension headers\n *       are not supported with this feature. This feature\n *       cannot be set in features for a device with\n *       NETIF_F_HW_CSUM also set.

No local access is required.\nAC:L - On a BIG-TCP-enabled host with an affected NIC (bnxt/mlx4/ice or a bond/bridge over them) every IPv6 jumbogram deterministically takes the `sw_checksum` path and hits the WARN \u2014 there is no race, no timing window, and no memory-layout dependency; the attacker only has to move more than 64KB of TCP data.\nPR:N - No credentials are needed \u2014 forwarded transit traffic or an ordinary request to an unauthenticated network service is sufficient to make the victim emit a jumbogram. Locally, any unprivileged user with a TCP/IPv6 socket also reaches the same code with no capabilities.\nUI:N - Triggering requires only that the target transmit or forward IPv6 TCP data, which the attacker induces directly by sending or requesting traffic. No action by any local user or administrator is involved.\nS:U - The WARN, the packet drop and the log output all occur within the kernel\u0027s own security authority on the affected host; no VM, IOMMU, or sandbox boundary is crossed.\nC:L - The WARN path calls `skb_dump(KERN_WARNING, skb, false)`, which hex-dumps the packet\u0027s headers plus up to `MAX_HEADER + 128` bytes of in-flight payload, along with socket and device metadata, into the kernel log \u2014 a small, bounded disclosure of live network data readable by anyone with dmesg access. It is not an arbitrary read, so the leak is limited rather than high.\nI:N - There is no memory corruption and no out-of-bounds write; the affected packet is discarded by `kfree_skb()` in `validate_xmit_skb()` rather than transmitted with altered contents, so no data is modified.\nA:H - `skb_warn_bad_offload()` issues a `WARN(1, ...)`, which panics the machine outright on the many production and hardened deployments running with `panic_on_warn=1`; even without that, every BIG TCP packet is unconditionally dropped, breaking or severely degrading IPv6 TCP connectivity while flooding the log with splats and packet dumps."
