CVE-2026-64337

CVE-2026-64337 affects the Linux kernel's USB MTU3 gadget driver . The function mtu3_gadget_queue() maps the request DMA before checking whether the QMU GPD ring can accept another transfer. When mtu3_prepare_transfer() fails, the request is returned with -EAGAIN but the DMA mapping is never unma...

CVE-2026-64321

CVE-2026-64321 is a reference count leak in the NVMe over RDMA (nvmet_rdma) target of the Linux kernel. In nvmet_rdma_queue_connect(), a call to nvmet_rdma_find_get_device() acquires an ndev reference via kref_get(), but on the early-return path triggered when the host queue backlog is exceeded (...
