CVE-2026-64290

A flaw was found in the Linux kernel's iommufd component. When a copytouser operation fails within the iommufdfaultfopsread function, the system enters an infinite loop. This continuous retry consumes 100% of the CPU and holds a mutex, which can lead to a denial of service DoS for affected system...
