IBM i PTF Guide, Volume 28, Number 22

July 13, 2026 Doug Bidwell

We have been catching up and are almost caught up after the big move to Pennsylvania. This week, we have a slew of software vulnerabilities to tell you about, and also a bunch of HIPER fixes for NVM-Express flash drives on Power Systems running IBM i. Let’s start with the flash issue, since this is the one that is going to affect a lot of people.

IBM says that during unit testing an issue was found “where a NAND management that could result in command timeouts as well as several power cycling related hangs.” This issue affects the following devices:

IBM 5B53 enterprise-grade 800GB PCIe Gen4 NVMe U.2 solid-state drive
IBM 5B52 enterprise 1.6 TB Gen4 NVMe SSD module
IBM 5B51 ES5E enterprise 3.2 TB NVMe U.2 SSD module
IBM 5B50 high-performance 6.4 TB Enterprise NVMe U.2 SSD module

The following HIPER PTFs have been put out to fix the issue:

IBM i Release	5770-999	PTF Number(s)
730			        MJ09644
740			        MJ09645
750			        MJ09649
760			        MJ09650

Now, to the security vulnerabilities.

First, we have Security Bulletin: IBM i is Affected By Multiple Vulnerabilities in Navigator for i and Digital Certificate Manager, for which you can find more at this link. The remediation/fixes are as follows, by IBM i release:

5770-SS1	PTF Number(s)	
7.6	        SJ10004
7.5	        SJ10016
7.4	        SJ10019
7.3	        SJ10020
5770-SS1 Opt 34	PTF Number(s)
7.6	        SJ10556
7.5	        SJ10555
7.4	        SJ10554
7.3	        SJ10553

Second, we have Security Bulletin: Vulnerability in BIND (CVE-2026-3592, CVE-2026-5946) affects AIX/ VIOS. More information is at this link. The affected products are AIX 7.2 and 7.4 as well as VIOS 4.1. Third, we have the similar but different Security Bulletin: Vulnerability in BIND (CVE-2025-13878) affects AIX/ VIOS, with more information at this link, and fourth, the also similar Security Bulletin: Vulnerability in BIND (CVE-2025-13878) affects AIX/ VIOS (with a link here for more data on it) and fifth, the nearly identical title Security Bulletin: Vulnerability in BIND (CVE-2026-1519) affects AIX/ VIOS (with a link here for more information). The affected products are also AIX 7.2 and 7.4 and VIOS 4.1.

Sixth, we have Security Bulletin: IBM i is Affected by Algorithm Downgrade in Transport Layer Security [CVE-2026-4942], with more information here. The PTF fixes for this issue are:

IBM i Release	5770-SS1	PTF Number(s)
7.6			        MJ09141
7.5			        MJ09140
7.4			        MJ09139
7.3			        MJ09138

That should keep you busy for a while.
