"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbnge: Fix NULL pointer dereference in aux device release\n\nIf allocation of auxr_dev fails during auxiliary device setup, the error\npath calls auxiliary_device_uninit(), which eventually invokes\nbnge_aux_dev_release().\n\nThe release callback unconditionally dereferences aux_priv->auxr_dev->pdev\nto retrieve the parent bnge_dev. Since auxr_dev has not yet been allocated\non this failure path, the dereference results in a NULL pointer exception\n\nRetrieve the parent bnge_dev from the auxiliary device's parent instead of\nauxr_dev, and free auxr_dev only when it was successfully allocated. This\nallows the release callback to correctly clean up partially initialized\nauxiliary devices."
