In the Linux kernel, the following vulnerability has been resolved: team: Move team device type change at the end of team_port_add Attempting to add a port device that is already up will expectedly fail, but not before modifying the team device header_ops. In the case of the syzbot reproducer the gre0 device is already in state UP when it attempts to add it as a port device of team0, this fails but before that header_ops->create of team0 is changed from eth_header to ipgre_header in the call to team_dev_type_check_change. Later when we end up in ipgre_header() struct ip_tunnel* points to nonsense as the private data of the device still holds a struct team. Example sequence of iproute2 commands to reproduce the hang/BUG(): ip link add dev team0 type team ip link add dev gre0 type gre ip link set dev gre0 up ip link set dev gre0 master team0 ip link set dev team0 up ping -I team0 1.1.1.1 Move team_dev_type_check_change down where all other checks have passed as it changes the dev type with no way to restore it in case one of the checks that follow it fail. Also make sure to preserve the origial mtu assignment: - If port_dev is not the same type as dev, dev takes mtu from port_dev - If port_dev is the same type as dev, port_dev takes mtu from dev This is done by adding a conditional before the call to dev_set_mtu to prevent it from assigning port_dev->mtu = dev->mtu and instead letting team_dev_type_check_change assign dev->mtu = port_dev->mtu. The conditional is needed because the patch moves the call to team_dev_type_check_change past dev_set_mtu. Testing: - team device driver in-tree selftests - Add/remove various devices as slaves of team device - syzbot

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.

  - team: Move team device type change at the end of team_port_add Attempting to add a port device that is     already up will expectedly fail, but not before modifying the team device header_ops. In the case of the     syzbot reproducer the gre0 device is already in state UP when it attempts to add it as a port device of     team0, this fails but before that header_ops->create of team0 is changed from eth_header to ipgre_header     in the call to team_dev_type_check_change. Later when we end up in ipgre_header() struct ip_tunnel* points     to nonsense as the private data of the device still holds a struct team. Example sequence of iproute2     commands to reproduce the hang/BUG(): ip link add dev team0 type team ip link add dev gre0 type gre ip     link set dev gre0 up ip link set dev gre0 master team0 ip link set dev team0 up ping -I team0 1.1.1.1 Move     team_dev_type_check_change down where all other checks have passed as it changes the dev type with no way     to restore it in case one of the checks that follow it fail. Also make sure to preserve the origial mtu     assignment: - If port_dev is not the same type as dev, dev takes mtu from port_dev - If port_dev is the     same type as dev, port_dev takes mtu from dev This is done by adding a conditional before the call to     dev_set_mtu to prevent it from assigning port_dev->mtu = dev->mtu and instead letting     team_dev_type_check_change assign dev->mtu = port_dev->mtu. The conditional is needed because the patch     moves the call to team_dev_type_check_change past dev_set_mtu. Testing: - team device driver in-tree     selftests - Add/remove various devices as slaves of team device - syzbot (CVE-2025-68340)

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