CVE-2026-89795

CVE-2026-89795 affects the Linux kernel PCI hotplug driver on s390 systems that use a machine-level hypervisor. The root cause is that pci_create_slot() assigns a single shared pci_slot object to multifunction PCI devices; when a function is reset via the hotplug reset_slot() interface, the wrong...

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-2026-74514

A flaw was found in the KVM Kernel-based Virtual Machine s390 PCI component. Incorrect memory accounting in the accountmem and unaccountmem functions, specifically related to the handling of pinned and unpinned pages, can lead to a resource leak. This occurs because the reference count for user...
