Description

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Handle partially initialized auxiliary devices

bnxt_aux_devices_init() calls auxiliary_device_init() before all fields used by bnxt_aux_dev_release() are initialized. After auxiliary_device_init() succeeds, later errors must unwind with auxiliary_device_uninit(), which invokes the release callback.

The release callback assumes that aux_priv->id, aux_priv->edev, edev->net and edev->ulp_tbl are all populated. If allocation fails after auxiliary_device_init(), the release path can otherwise dereference or clear partially initialized state.

Allocate and attach the bnxt_en_dev and ULP table before calling auxiliary_device_init(), so the release callback only sees a fully initialized auxiliary private object. If auxiliary_device_init() itself fails, free those allocations directly because device_initialize() has not run and the release callback will not be invoked.

This issue was found by a static analysis checker and confirmed by manual source review.
