In the Linux kernel, the following vulnerability has been resolved: ax25: fix incorrect dev_tracker usage While investigating a separate rose issue [1], and enabling CONFIG_NET_DEV_REFCNT_TRACKER=y, Bernard reported an orthogonal ax25 issue [2] An ax25_dev can be used by one (or many) struct ax25_cb. We thus need different dev_tracker, one per struct ax25_cb. After this patch is applied, we are able to focus on rose.
