CVE-2021-47266

CVE-2021-47266 affects the Linux kernel’s RDMA/IPOIB path. After a change that sets rtnl_link_ops for ipoib interfaces, moving an IPoIB device to a non-initial netns can cause the device to disappear when the owning netns is deleted, due to default_device_exit() skipping interfaces with rtnl_link...
