CVE-2026-43056 is a use-after-free vulnerability in the Linux kernel MANA network driver's add_adev() error path. When auxiliary_device_add() fails, cleanup calls auxiliary_device_uninit(), invoking adev_release() and freeing the containing struct mana_adev. Subsequent fall-through to the initialization-failure cleanup accesses adev->id through the embedded auxiliary device object after its storage has been freed. The vulnerability can potentially be triggered by a low-privileged local attacker, causing denial of service and possibly affecting confidentiality and integrity.
