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...

CVE-2026-72412

A flaw was found in the Linux kernel's memory management for s390 systems. An internal flag, intended to mark guest memory pages for discard after unmapping by the Kernel-based Virtual Machine KVM, was not consistently cleared when those pages were subsequently reused. This improper handling coul...
