UBUNTU-CVE-2025-21890: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Which systems are most likely to show evidence of this issue?

Systems using the idpf network driver are relevant. The described warning is triggered on kernels built with CONFIG_DEBUG_NET=y, during idpf_vport_splitq_napi_poll().

Q: How can I check whether the issue is occurring?

Check kernel logs for DEBUG_NET_WARN_ON_ONCE related to skb_transport_header_was_set(skb), with a stack trace involving idpf_vport_splitq_napi_poll. The provided example shows the warning occurring while the idpf module is loaded.

Updated

In the Linux kernel, the following vulnerability has been resolved: idpf: fix checksums set in idpfrxrsc() idpfrxrsc() uses skbtransportoffset(skb) while the transport header is not set yet. This triggers the following warning for CONFIGDEBUGNET=y builds.
