CVE-2023-53307
rbd: avoid use-after-free in do_rbd_add() when rbd_dev_create() fails
Description
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 <[email protected]>.
