CVE-2026-74515

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine s390 PCI component. This vulnerability arises from improper handling of adapter interrupt forwarding, where enabling it multiple times for a zPCI device without prior unregistration can lead to resource overwriting and leakag...

CVE-2026-72290

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for s390 PCI. During the setup of guest interrupt forwarding, a reference count refcount to the Guest Interrupt Service Call GISC may not be properly released if subsequent setup steps fail. This resource leak can lead to...

CVE-2026-74515

CVE-2026-74515 concerns the Linux kernel, specifically KVM on s390 for PCI (zPCI). The issue arises when enabling adapter interrupt forwarding: the MPCIFC instruction forbids registering interrupts without unregistering first, so a second or repeated enable request for the same device is rejected...
