Overview

CVE-2023-53322 is a high-severity vulnerability. It was published on September 16, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

scsi: qla2xxx: Wait for io return on terminate rport

System crash due to use after free.

Current code allows terminate_rport_io to exit before making

sure all IOs has returned. For FCP-2 device, IO's can hang

on in HW because driver has not tear down the session in FW at

first sign of cable pull. When dev_loss_tmo timer pops,

terminate_rport_io is called and upper layer is about to

free various resources. Terminate_rport_io trigger qla to do

the final cleanup, but the cleanup might not be fast enough where it

leave qla still holding on to the same resource.

Wait for IO's to return to upper layer before resources are freed.

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.
