Echo: linux: security update to 6.1.153-1

high Tenable Self-Hosted Container Security Plugin ID 460895

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: mptcp: plug races between subflow fail
 and subflow creation We have races similar to the one addressed by the previous patch between subflow
 failing and additional subflow creation. They are just harder to trigger. The solution is similar. Use a
 separate flag to track the condition 'socket state prevent any additional subflow creation' protected by
 the fallback lock. The socket fallback makes such flag true, and also receiving or sending an MP_FAIL
 option. The field 'allow_infinite_fallback' is now always touched under the relevant lock, we can drop the
 ONCE annotation on write. (CVE-2025-38552)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
