CVE-2026-74312

The CVE-2026-74312 entries describe a Linux kernel vulnerability in vhost/vdpa where mmap and fault paths use vma->vm_pgoff as a virtqueue index without proper bounds validation against v->nvqs. This allowed an out-of-range queue index to reach driver callbacks via get_vq_notification(), un...
