CVE-2026-74312 vhost/vdpa: validate virtqueue index in mmap and fault paths

In the Linux kernel, the following vulnerability has been resolved: vhost/vdpa: validate virtqueue index in mmap and fault paths vhostvdpammap and vhostvdpafault use vma-vmpgoff as a virtqueue index for getvqnotification, but they do not validate that the index is smaller than v-nvqs. The ioctl...

CVE-2026-74310 vhost/net: complete zerocopy ubufs only once

In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubufinfo per outstanding zerocopy TX descriptor and hands it to the backend socket. The networking stack may then clone a zerocopy skb before all skb referenc...

CVE-2026-74310

The CVE affects the Linux kernel vhost/net zerocopy path. The bug arises when vhost_zerocopy_complete() treats every ubuf callback as a completed descriptor, dereferences ubuf->ctx, and updates state while a cloned skb still holds the same ubuf_info refcount. This can allow a backend reset to ...

CVE-2026-72084

The CVE-2026-72084 vulnerability affects the Linux kernel SCSI subsystem: PR-OUT TransportID parsing for iSCSI can over-read when the provided buffer length isn’t properly validated, potentially allowing out-of-bounds reads. The fix introduces length checks on the iSCSI TransportID (ADDITIONAL LE...
