IBM i PTF Guide, Volume 28, Numbers 1 Through 3

January 19, 2026 Doug Bidwell

We are determined to get you all caught up on the happenings with PTF patches and such that have happened so far in the new year after getting you caught up with what happened at the end of 2025 in last week’s issue.

So, without further ado, here are the first three editions of the IBM i PTF Guide for 2026, which will end our “Ketchup” Weeks until the next holiday rolls along. (Technically, it is Martin Luther King day in America as we go to press, which is a holiday for many but not for all.)

We will start with Volume 28, Number 1, which was put together on January 3. There was not a lot going on then excepting a security vulnerability in the IBM i stack, which you can see in Security Bulletin: IBM i is affected by exposure of sensitive information and improper access control vulnerabilities in IBM Java SDK and IBM Java Runtime [CVE-2025-53066, CVE-2025-53057] and which has this link for more details. The patches for each release are as follows:

IBM recommends installing the 5770-JV1 PTF Group to receive all the latest PTF(s) which includes all PTFs in the above table. Here they are:
