UBUNTU-CVE-2025-21865: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: What configuration is needed to trigger this issue?

The described trigger involves at least two network namespaces and a GTP device in one namespace whose UDP socket belongs to another namespace. During network-namespace cleanup, the same GTP device can then be processed for deletion twice.

Q: What evidence would indicate that a system has encountered the problem?

The reported symptom is a list_del() corruption splat during gtp_net_exit_batch_rtnl() while network namespaces are being dismantled. The issue occurs in the device deletion path when gtp_dellink() is invoked more than once for the same device.

Q: Which Ubuntu kernel package variants are listed as affected?

The listed software includes linux, linux-azure, linux-aws, linux-gcp, linux-realtime, linux-hwe-edge, linux-bluefield, and linux-ibm.

Updated

In the Linux kernel, the following vulnerability has been resolved: gtp: Suppress list corruption splat in gtpnetexitbatchrtnl(). Brad Spengler reported the listdel() corruption splat in gtpnetexitbatchrtnl(). [0] Commit eb28fd76c0a0 ("gtp: Destroy device along with udp socket's netns dismantle.") added the foreachnetdev() loop in gtpnetexitbatchrtnl() to destroy devices in each netns as done in geneve and ip tunnels. However, this could trigger ->dellink() twice for the same device during ->exitbatchrtnl(). Say we have two netns A & B and gtp device B that resides in netns B but whose UDP socket is in netns A. 1. cleanupnet() processes netns A and then B. 2. gtpnetexitbatchrtnl() finds the device B while iterating netns A's gn->gtpdevlist and calls ->dellink(). [ device B is not yet unlinked from netns B as unregisternetdevicemany() has not been called. ] 3. gtpnetexitbatchrtnl() finds the device B while iterating netns B's foreachnetdev() and calls ->dellink(). gtpdellink() cleans up the device's hash table, unlinks the dev from gn->gtpdevlist, and calls unregisternetdevicequeue(). Basically, calling gtpdellink() multiple times is fine unless CONFIGDEBUGLIST is enabled. Let's remove foreachnetdev() in gtpnetexitbatchrtnl() and delegate the destruction to defaultdeviceexitbatch() as done in bareudp.

Compensating control
In gtp_net_exit_batch_rtnl(), remove the for_each_netdev() loop and delegate device destruction to default_device_exit_batch(), as done in bareudp, to prevent gtp_dellink() from being called twice for the same device.

Frequently Asked Questions

What configuration is needed to trigger this issue?

The described trigger involves at least two network namespaces and a GTP device in one namespace whose UDP socket belongs to another namespace. During network-namespace cleanup, the same GTP device can then be processed for deletion twice.

What evidence would indicate that a system has encountered the problem?

The reported symptom is a list_del() corruption splat during gtp_net_exit_batch_rtnl() while network namespaces are being dismantled. The issue occurs in the device deletion path when gtp_dellink() is invoked more than once for the same device.

Which Ubuntu kernel package variants are listed as affected?

The listed software includes linux, linux-azure, linux-aws, linux-gcp, linux-realtime, linux-hwe-edge, linux-bluefield, and linux-ibm.
