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...

EUVD-2026-59457

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 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 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 scsi: target: Bound PR-OUT TransportID parsing to the received buffer

In the Linux kernel, the following vulnerability has been resolved: scsi: target: Bound PR-OUT TransportID parsing to the received buffer corescsi3decodespeciport and corescsi3emulateregisterandmove hand the raw PERSISTENT RESERVE OUT parameter buffer to targetparseprouttransportid without tellin...

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...

CVE-2026-74312: Undefined Security Weakness

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...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the vhost/vdpa component where the functions vhost vdpa mmap and vhost vdpa fault use vma-vm pgoff as a virtqueue index for get vq notification without validating that...

CVE-2026-74356: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: vhost: fix vhostgetavailidx for a non empty ring vhostgetavailidx is supposed to report whether it has updated vq-availidx. Instead, it returns whether all entries have been consumed, which is usually the same. But not always - i...

PT-2026-72746

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A slab-use-after-free issue exists in the vhost-net component of the Linux kernel. The vhost zerocopy complete function incorrectly treats every ubuf callback as a completed vhost...
