Title
rbd: avoid use-after-free in do_rbd_add() when rbd_dev_create() fails
Summary
In the Linux kernel, the following vulnerability has been resolved:
rbd: avoid use-after-free in do_rbd_add() when rbd_dev_create() fails
If getting an ID or setting up a work queue in rbd_dev_create() fails,
use-after-free on rbd_dev->rbd_client, rbd_dev->spec and rbd_dev->opts
is triggered in do_rbd_add(). The root cause is that the ownership of
these structures is transfered to rbd_dev prematurely and they all end
up getting freed when rbd_dev_create() calls rbd_dev_free() prior to
returning to do_rbd_add().
Found by Linux Verification Center (linuxtesting.org) with SVACE, an
incomplete patch submitted by Natalia Petrova <n.petrova@fintech.ru>.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
