March 23, 2026 Doug Bidwell

Happy Spring everyone! We are well into Daylight Savings Time and have longer – meaning brighter – evenings, so it is hard not to be optimistic about the spring, summer, and fall ahead. This week, we have one notice and two security vulnerabilities to start with. Let’s get to it.

Let’s start with the OSP-Distribution requisite for Technology Refresh PTF, which you can find out more about at this link. The PTFs are as follows:

For IBM i 7.4: FI0138771, which is PTF SJ09037
For IBM i 7.5: FI0138772, which is PTF SJ09038

Now, for the security vulnerabilities. First, we have Security Bulletin: IBM i is affected by a denial of service vulnerability [CVE-2026-1376], with more information here. The affected product is IBM i 7.6, 5733-SC1, and the fix is SJ09012.

Second, we have Security Bulletin: IBM i is affected by multiple vulnerabilities in OpenSSL, with more information available at this link. The matrix of affected products and PTFs for their fixes are as follows:

Affected Product(s)	Affected Version(s)	Affected Feature(s)		PTF Number
									        License Program 
IBM i	                7.6			5733-SC1			SJ08830
