Overview

CVE-2023-53307 is a high-severity vulnerability. It was published on September 16, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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]>.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
