RHSA-2026:89814kernel-rt security update Executive summary Red Hat has released a security update for the kernel-rt real-time Linux kernel packages used on Red Hat Enterprise Linux 8 systems. Red Hat rates the issue Moderate, and its recommendation is to install the update and reboot the affected systems. Technical summary The advisory fixes CVE-2026-74515, a kernel flaw in the KVM s390 PCI code that concerns adapter interrupt forwarding when it is already enabled, and the fix rejects that case. The advisory does not state the vulnerability class, attack vector, or preconditions, and it does not give a CVSS score in the text. The fixed package is kernel-rt-4.18.0-553.179.1.rt7.520.el8_10, and a reboot is required for the update to take effect. No workaround or detection guidance is stated, and no exploitation in the wild is mentioned. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
