UBUNTU-CVE-2025-38003: High severity ubuntu/linux-hwe-edge vulnerability

Q: Who is exposed to this issue?

Systems using the listed Ubuntu kernel packages are in scope: linux-azure, linux-gcp, linux-azure-fde, linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, and linux-realtime. Exploitation requires local access and low privileges.

Q: What does an attacker need to do to trigger the issue?

An attacker needs to race procfs content generation for a BCM operation against removal of that BCM operation. The vulnerable path can expose unreliable data through a use-after-free condition.

Q: What is the remediation?

Apply the Ubuntu kernel update that includes the upstream fix. The fix adds RCU read-side protection while generating the procfs content and removes list entries under RCU protection.

Published Jun 8, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved: can: bcm: add missing rcu read protection for procfs content When the procfs content is generated for a bcmop which is in the process to be removed the procfs output might show unreliable data (UAF). As the removal of bcmop's is already implemented with rcu handling this patch adds the missing rcureadlock() and makes sure the list entries are properly removed under rcu protection.

Frequently Asked Questions

Who is exposed to this issue?

Systems using the listed Ubuntu kernel packages are in scope: linux-azure, linux-gcp, linux-azure-fde, linux-aws-fips, linux-azure-fips, linux-fips, linux-gcp-fips, and linux-realtime. Exploitation requires local access and low privileges.

What does an attacker need to do to trigger the issue?

An attacker needs to race procfs content generation for a BCM operation against removal of that BCM operation. The vulnerable path can expose unreliable data through a use-after-free condition.

What is the remediation?

Apply the Ubuntu kernel update that includes the upstream fix. The fix adds RCU read-side protection while generating the procfs content and removes list entries under RCU protection.
