In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Fixed memory accounting for pinned/unpinned pages The accountmem and unaccountmem functions call getuid, which increments the reference count of struct userstruct on every invocation. However, we do not decrement...

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-2026-74515

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...
