Wasmtime: Preemption and traps during bulk operations enable breaking internal VM state

Impact Wasmtime's implementation of bulk-data-transfer WebAssembly instructions, such as memory.copy, contains a vulnerability when a preemption via epochs or fuel is combined with altering the store's state or cancelling a computation. To prevent these operations from taking too long Wasmtime...

CVE-2026-104855 Wasmtime: Preemption and traps during bulk operations enable breaking internal VM state

Wasmtime is a runtime for WebAssembly. From 46.0.0 until 46.0.2 and 47.0.3, fuel and epoch preemption checks inside bulk operations including memory.copy, table.grow, and array.copy can expose invalid intermediate state when an embedder mutates a Store in Store::epochdeadlinecallback or continues...

A flaw was found in KubeVirt's migration proxy. When spec.configuration.migrations.disableTLS is set to true on the KubeVirt custom resource, the target virt-handler binds a plain TCP listener on all interfaces 0.0.0.0/:: on a random port with no authentication, peer allow-list, or handshake toke...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV – Lock all vCPUs when synchronizing VMSAs for SNP launches to complete. Lock all vCPUs when synchronizing and encrypting VMSAs for SNP guests. Allowing the user space to manipulate or run a vCPU while its state is being...

CVE-2025-70956

A State Pollution vulnerability was discovered in the TON Virtual Machine TVM before v2025.04. The issue exists in the RUNVM instruction logic VmState::runchildvm, which is responsible for initializing child virtual machines. The operation moves critical resources specifically libraries and log...

[NetScaler-SDX] SVM Management UI displays "Halted" about VPX "VM State"

In a rare case, if you check the NetScaler VPX state on SVM UI, you may see "VM State" displays "Halted" with red light. Your VPX is actually healthy and you can logon VPX NSIP successfully. Business traffic is not impacted...

CVE-2014-3608

The VMWare driver in OpenStack Compute Nova before 2014.1.3 allows remote authenticated users to bypass the quota limit and cause a denial of service resource consumption by putting the VM into the rescue state, suspending it, which puts into an ERROR state, and then deleting the image. NOTE: thi...
