  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ixp4xx_hss: fix duplicate HDLC netdev allocation\n\nixp4xx_hss_probe() allocates two HDLC netdevs. The first one is stored\nin ndev, initialized, and registered with register_hdlc_device(). The\nsecond one is stored in port-\u003enetdev and later used by the remove path\nfor unregister_hdlc_device() and free_netdev().\n\nThis means that the registered netdev is not the same object that is\nunregistered and freed on remove. It also leaks the first allocation if\nthe second alloc_hdlcdev() call fails, and the first allocation is not\nchecked before ndev is used.\n\nOlder code allocated the HDLC netdev only once and stored the same object\nin both the local variable and port-\u003enetdev. The buggy conversion split\nthis into two alloc_hdlcdev() calls. A later rename changed the local\nvariable name to ndev, but the underlying mismatch remained.\n\nFix this by allocating the HDLC netdev only once and assigning the same\nobject to port-\u003enetdev.",
