In the Linux kernel, the following vulnerability has been resolved:

fou: remove warn in gue_gro_receive on unsupported protocol

Drop the WARN_ON_ONCE inn gue_gro_receive if the encapsulated type is not known or does not have a GRO handler.

Such a packet is easily constructed. Syzbot generates them and sets off this warning.

Remove the warning as it is expected and not actionable.

The warning was previously reduced from WARN_ON to WARN_ON_ONCE in commit 270136613bf7 ("fou: Do WARN_ON_ONCE in gue_gro_receive for bad proto callbacks").

Severity

              "value": "AV:N - The warning is reached from the NAPI GRO receive path (`udp4_gro_receive` \u2192 `gue_gro_receive`) while parsing a UDP datagram arriving from the wire on a host with a FOU/GUE tunnel port, so any remote host that can send a UDP packet to that port triggers it.\nAC:L - The trigger is a single stateless, unsolicited UDP packet whose GUE header carries any `proto_ctype` lacking a registered offload handler; the commit itself notes \"such a packet is easily constructed\" and syzbot generates them, with no race, memory-layout, or timing condition involved.\nPR:N - The GRO path processes the packet before any authentication, authorization, or socket-level filtering \u2014 the FOU receive socket is unconnected, so an unauthenticated off-path attacker needs no credentials on the target.\nUI:N - Processing happens automatically in softirq context when the packet is received; no action by any local user or administrator is required.\nS:U - The warning and any resulting panic occur in the kernel of the receiving host, entirely within the same security authority, with no crossing of a VM, container, or IOMMU boundary.\nC:N - Control flow after the WARN is identical to the fixed code (`goto out`); no memory is read out of bounds and nothing is disclosed to the attacker, who cannot observe the kernel log.\nI:N - The bug involves no memory corruption or state modification \u2014 the packet is dropped from GRO either way, so no attacker-controlled data is written anywhere.\nA:H - The attacker-triggerable WARN_ON_ONCE becomes an immediate kernel panic on systems configured with `panic_on_warn=1` or a `warn_limit`, a common hardening/crash-dump setting in production, cloud, and Android fleets, allowing a single remote packet to take down the host."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
