UBUNTU-CVE-2025-38326: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Which systems are exposed to this hang?

Systems using an AoE device are exposed when that device is taken down while its rq_list still contains accepted block requests waiting to be transmitted to the AoE target. The affected Ubuntu kernel packages listed are linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, linux-azure, linux-gcp, linux-azure-fde, and linux-realtime.

Q: What is required to trigger the issue?

An attacker or local actor needs the ability to cause an AoE device to be downed while pending accepted block requests remain in its rq_list. The resulting blk_mq_freeze_queue() call can wait indefinitely for those requests and hang the system.

Q: How can I recognize that this issue may already be affecting a system?

A likely symptom is an indefinite hang during an AoE device shutdown or removal operation, with blk_mq_freeze_queue() waiting for requests that were queued for transmission to the AoE target.

Published Jul 10, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: aoe: clean device rqlist in aoedevdowndev() An aoe device's rqlist contains accepted block requests that are waiting to be transmitted to the aoe target. This queue was added as part of the conversion to blkmq. However, the queue was not cleaned out when an aoe device is downed which caused blkmqfreezequeue() to sleep indefinitely waiting for those requests to complete, causing a hang. This fix cleans out the queue before calling blkmqfreezequeue().

Frequently Asked Questions

Which systems are exposed to this hang?

Systems using an AoE device are exposed when that device is taken down while its rq_list still contains accepted block requests waiting to be transmitted to the AoE target. The affected Ubuntu kernel packages listed are linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, linux-azure, linux-gcp, linux-azure-fde, and linux-realtime.

What is required to trigger the issue?

An attacker or local actor needs the ability to cause an AoE device to be downed while pending accepted block requests remain in its rq_list. The resulting blk_mq_freeze_queue() call can wait indefinitely for those requests and hang the system.

How can I recognize that this issue may already be affecting a system?

A likely symptom is an indefinite hang during an AoE device shutdown or removal operation, with blk_mq_freeze_queue() waiting for requests that were queued for transmission to the AoE target.
