IBM i PTF Guide, Volume 28, Number 5

February 2, 2026 Doug Bidwell

This week there’s another winter storm whacking the eastern half of the United States, and we are also putting together the IBM i PTF Guide a little early in case some of the people working on The Four Hundred lose power. If all goes well, and you are reading this on Monday, then we got it all done before anything bad happened.

This week, we start off with two security vulnerabilities.

First, we have Security Bulletin: Multiple Vulnerabilities in IBM Java SDK affect IBM WebSphere Application Server and WebSphere Application Server Liberty due to the January 2026 CPU, which you can find out more about at this link. The affected products and versions are:

Affected Product(s)			Version(s)
WebSphere Application Server		9.0
WebSphere Application Server		8.5
WebSphere Application Server - Liberty	Continuous delivery

See the link for additional details and remediation!

Second, we have Security Bulletin: IBM WebSphere Application Server Liberty is affected by a remote code execution vulnerability (CVE-2025-14914), about which you can get more information here. This vulnerability affects WebSphere Application Server – Liberty, versions 17.0.0.3 through 26.0.0.1.
