July 20, 2026 Doug Bidwell

It is Ketchup Week here at the IBM i PTF Guide once again, and Big Blue made it a little more interesting by announcing the Technology Refreshes for IBM i 7.6 and IBM i 7.5 last week.

Let’s dive in, starting with Volume 28, Number 23, dated July 11 and beginning with two bugs and two security vulnerabilities you need to be aware of.

First, we have Security Bulletin: Multiple vulnerabilities in IBM Rational Developer for i, which you can find out more about here. IBM strongly recommends addressing the vulnerability now by upgrading. This upgrade fixes 15+ CVE issues at this time – see the link for details. Alternatively, the fix is available at Downloads. This vulnerability affects IBM Rational Developer for i 9.9.0.0 – 9.9.0.3, and an interim fix 9.9.0.4 for IBM Rational Developer for i is available. Use ‘Help>Check for Updates’ from within the product to install the fix.

Second, we have Security Bulletin: IBM i is Affected by Multiple Vulnerabilities in IBM Java SDK and IBM Java Runtime [CVE-2026-22016, CVE-2026-22021, CVE-2026-22013, CVE-2026-22018, CVE-2026-34268, CVE-2026-22007], with more information available at this link. The fixes by release are as follows:

7.6	        7.5		7.4		7.3
SJ09782	        SJ09781		SJ09780		SJ09779
SJ09786	        SJ09785		SJ09784		SJ09783
SJ09767	        SJ09766		SJ09765		SJ09764	
SJ09771	        SJ09770		SJ09769		SJ09768
SJ09737	        SJ09734		SJ09733		SJ09443
SJ09742	        SJ09739		SJ09738		SJ09444
SJ09754	        SJ09736		SJ09735	
SJ09756	        SJ09741		SJ09740	
	        SJ09753		
	        SJ09755

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

7.6	SF99965 Level 6		
7.5	SF99955 Level 21		
7.4	SF99665 Level 33		
7.3	SF99725 Level 42

Third, we have a bug where IBM i 7.6 and 7.5 HTTP Server CGI Programs Fail with MCH3601 After IBM i HTTP Group PTF Apply, and you can see more about this issue at this link. Here are more details:

Upgrading Apache to version 2.4.65 results in MCH3601 failures in the following levels:

IBM i 7.6 — SF99962 levels 9 and 10
IBM i 7.5 — SF99952 levels 28 and 29

Problematic individual PTFs included in these group levels:

IBM i 7.6 — SJ09530, superseded by SJ10029
IBM i 7.5 — SJ09477, superseded by SJ10030

Please review the above link for issues and workarounds. New groups have been created for 7.6 and 7.6 HTTP Server, do not apply the levels above if you have ordered or received them, reorder and apply the latest groups instead. If you have already applied the above groups, then please read the link for to resolve any issues.

And fourth, we have a bug called IBM i Java Development Kit 8 64 & 32 bit VMs Fail with “Could not generate ECDHEMLKEM keypair” After IBM i Java Group PTF Apply, with more information available here. The affected IBM i Java Group PTF Levels Providing Java 8 SR8 FP55 are as follows:

IBM i 7.6 – SF99965 level 4
IBM i 7.5 – SF99955 level 19
IBM i 7.4 – SF99665 level 31
IBM i 7.3 – SF99725 level 40
