In the Linux kernel, the following vulnerability has been resolved: openvswitch: fix lockup on tx to unregistering netdev with carrier Commit in a fixes tag attempted to fix the issue in the following sequence of calls: do_output -> ovs_vport_send -> dev_queue_xmit -> __dev_queue_xmit -> netdev_core_pick_tx -> skb_tx_hash When device is unregistering, the 'dev->real_num_tx_queues' goes to zero and the 'while (unlikely(hash >= qcount))' loop inside the 'skb_tx_hash' becomes infinite, locking up the core forever. But unfortunately, checking just the carrier status is not enough to fix the issue, because some devices may still be in unregistering state while reporting carrier status OK. One example of such device is a net/dummy. It sets carrier ON on start, but it doesn't implement .ndo_stop to set the carrier off. And it makes sense, because dummy doesn't really have a carrier. Therefore, while this device is unregistering, it's still easy to hit the infinite loop in the skb_tx_hash() from the OVS datapath. There might be other drivers that do the same, but dummy by itself is important for the OVS ecosystem, because it is frequently used as a packet sink for tcpdump while debugging OVS deployments. And when the issue is hit, the only way to recover is to reboot. Fix that by also checking if the device is running. The running state is handled by the net core during unregistering, so it covers unregistering case better, and we don't really need to send packets to devices that are not running anyway. While only checking the running state might be enough, the carrier check is preserved. The running and the carrier states seem disjoined throughout the code and different drivers. And other core functions like __dev_direct_xmit() check both before attempting to transmit a packet. So, it seems safer to check both flags in OVS as well.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: openvswitch: fix lockup on tx to     unregistering netdev with carrier Commit in a fixes tag attempted to fix the issue in the following     sequence of calls: do_output -> ovs_vport_send -> dev_queue_xmit -> __dev_queue_xmit ->     netdev_core_pick_tx -> skb_tx_hash When device is unregistering, the 'dev->real_num_tx_queues' goes to     zero and the 'while (unlikely(hash >= qcount))' loop inside the 'skb_tx_hash' becomes infinite, locking up     the core forever. But unfortunately, checking just the carrier status is not enough to fix the issue,     because some devices may still be in unregistering state while reporting carrier status OK. One example of     such device is a net/dummy. It sets carrier ON on start, but it doesn't implement .ndo_stop to set the     carrier off. And it makes sense, because dummy doesn't really have a carrier. Therefore, while this device     is unregistering, it's still easy to hit the infinite loop in the skb_tx_hash() from the OVS datapath.
    There might be other drivers that do the same, but dummy by itself is important for the OVS ecosystem,     because it is frequently used as a packet sink for tcpdump while debugging OVS deployments. And when the     issue is hit, the only way to recover is to reboot. Fix that by also checking if the device is running.
    The running state is handled by the net core during unregistering, so it covers unregistering case better,     and we don't really need to send packets to devices that are not running anyway. While only checking the     running state might be enough, the carrier check is preserved. The running and the carrier states seem     disjoined throughout the code and different drivers. And other core functions like __dev_direct_xmit()     check both before attempting to transmit a packet. So, it seems safer to check both flags in OVS as well.
    (CVE-2025-21681)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4076 advisory.
