CVE-2026-74314 bpf: Cancel special fields on map value recycle
In the Linux kernel, the following vulnerability has been resolved: bpf: Cancel special fields on map value recycle Map update and delete paths currently call bpfobjfreefields when a value is being replaced or recycled. That makes field destruction depend on the context of the update/delete...
CVE-2026-74313
In the Linux kernel, the following vulnerability has been resolved: vduse: hold vduselock across IDR lookup in open path vdusedevopen looks up struct vdusedev through the IDR and then acquires dev-lock only after vduselock has been dropped. This leaves a window where a concurrent VDUSEDESTROYDEV...

CVE-2026-74314
CVE-2026-74314 relates to the Linux kernel BPF map value handling. The description shows a fix for canceling field cleanup on map value recycle: during updates/deletes, fields no longer are eagerly freed via bpf_obj_free_fields(); instead, bpf_obj_cancel_fields() performs only NMI-safe cleanup fo...
CVE-2026-74313
The CVE-2026-74313 issue affects the Linux kernel under the VDUSE path. Specifically, vduse_dev_open() currently looks up a vduse_dev via an IDR lookup and then acquires dev->lock after vduse_lock is dropped, creating a window where VDUSE_DESTROY_DEV could remove and free the same object befor...

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-2026-74312
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...

CVE-2026-74311
CVE-2026-74311 affects the Linux kernel virtio rtc path. The bug occurs when viortc_restore() calls viortc_init_vqs() without removing old virtqueues, enabling vp_del_vqs() to reference a NULL info pointer in vp_del_vq() and crash the guest kernel during restore. The fix deletes stale virtqueues ...
CVE-2026-74311 virtio: rtc: tear down old virtqueues before restore
In the Linux kernel, the following vulnerability has been resolved: virtio: rtc: tear down old virtqueues before restore virtiodevicerestore resets the device and restores the negotiated features before calling -restore. viortcfreeze intentionally leaves the existing virtqueues in place so the...
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
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 ...
