        Installed on my test server, not running XOSTOR, everything seems to be working fine so far.

            New security update candidates for you to test!

            Yet more vulnerabilities in Intel hardware, addressed in two complementary ways: patching Xen and updating Intel microcode.

            Together with this security update, will also publish a patched XAPI to fix a minor issue with information reporting from VM to hypervisor.

            Test on XCP-ng 8.2

            From an up-to-date host:

            yum clean metadata --enablerepo=xcp-ng-candidates
            yum update --enablerepo=xcp-ng-candidates
            reboot
            

            The usual update rules apply: pool coordinator first, etc.

            Versions

            • microcode_ctl: 2.1-26.xs29.8.xcpng8.2 (weird identifier for historical reasons, but that's actually Intel microcode published by them yesterday)
            • xen: 4.13.5-9.49.1.xcpng8.2
            • xapi: 1.249.41-1.2.xcpng8.2

            What to test

            Normal use and anything else you want to test. The closer to your actual use of XCP-ng, the better.

            Test window before official release of the updates

            ~24h. That's an urgent one.

              Installed and seems to be running fine so far on my test systems.

                @stormi I needed an excuse to reboot all my hosts... Upgraded and running on stable pools. I see the Intel 11th gen new microcode. All working normally at this time.

                      New update candidates for you to test!

                      A new batch of non-urgent updates is ready for user tests before a future collective release.

                      • openssh: Fix low priority CVE-2025-26465 DoS attack when VerifyHostKeyDNS is "yes" or "ask" (The Default value has not changed: "no")
                      • samba: Fix vulnerabilities which are very unlikely to be exploitable on XCP-ng but are reported by security scanners.
                      • xcp-ng-release: This update adds a certificate to resolve a TLS handshake error, particularly when deploying XOA from CLI using curl.

                      Test on XCP-ng 8.2

                      From an up to date host:

                      yum clean metadata --enablerepo=xcp-ng-testing
                      yum update --enablerepo=xcp-ng-testing
                      reboot
                      

                      The usual update rules apply: pool coordinator first, etc.

                      No specific steps for these updates for XOSTOR users.

                      Versions

                      • openssh: 7.4p1-23.3.2.xcpng8.2
                      • samba: 4.10.16-25.el7_9
                      • xcp-ng-release: 8.2.1-16

                      What to test

                      Normal use and anything else you want to test. The closer to your actual use of XCP-ng, the better.

                      Test window before official release of the updates

                      None defined, but early feedback is always better than late feedback, which is in turn better than no feedback 🙂

                        New security and maintenance update candidate

                        A new XSA (Xen Security Advisory) was published on the 1st of July, and an update to Xen addresses it. We also publish other non-urgent updates which we had in the pipe for the next release.


                        Security updates

                        • xen-*:
                          • Fix XSA-470 - An unprivileged guest can cause a hypervisor crash, causing a Denial of Service (DoS) of the entire host.

                        Maintenance updates

                        • openssh: fix low priority CVE-2025-26465 DoS attack when VerifyHostKeyDNS is "yes" or "ask" (The Default value has not changed: "no")
                        • samba: fix low priority CVEs on client side.
                        • xcp-ng-release: this update adds a certificate to resolve a TLS handshake error, particularly when deploying xoa.io.

                        Test on XCP-ng 8.2

                        yum clean metadata --enablerepo=xcp-ng-testing
                        yum update --enablerepo=xcp-ng-testing
                        reboot
                        

                        The usual update rules apply: pool coordinator first, etc.

                        Versions:

                        • openssh: 7.4p1-23.3.2.xcpng8.2
                        • samba: 4.10.16-25.el7_9
                        • xcp-ng-release: 8.2.1-16
                        • xen: 4.13.5-9.49.2.xcpng8.2

                        What to test

                        Normal use and anything else you want to test.

                        Test window before official release of the updates

                        ~2 days.

                          @gduperrey Installed and running on a few pools. Working correctly as expected.
