CVE-2026-23425

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for ARM64 architectures. This vulnerability arises from improper initialization of ID registers for non-protected pKVM protected KVM guests. A malicious guest operating system could exploit this by causing the hypervisor, the...

CVE-2026-34593 Ash Framework: Ash.Type.Module.cast_input/2 atom exhaustion via unchecked Module.concat allows BEAM VM crash

Ash Framework is a declarative, extensible framework for building Elixir applications. Prior to version 3.22.0, Ash.Type.Module.castinput/2 unconditionally creates a new Erlang atom via Module.concatvalue for any user-supplied binary string that starts with "Elixir.", before verifying whether the...

CVE-2026-34593

This CVE affects Ash Framework (Elixir) where Ash.Type.Module.cast_input/2 unconditionally creates a new Erlang atom via Module.concat([value]) for inputs starting with "Elixir." before module existence is verified. The atom creation can exhaust BEAM’s atom table (default ~1,048,576 entries) and ...

nodejs: Nodejs uninitialized memory exposure

A memory exposure flaw has been discovered in Node.js. A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other...

CVE-2026-23401

CVE-2026-23401: In the Linux kernel KVM x86/mmu, a race allowed installing an MMIO SPTE without first zapping an existing shadow-present SPTE when guest memory writes occurred outside KVM’s scope. This could enable a guest‑memory–related fault to leave a shadow SPTE intact when an MMIO SPTE is in...

GHSA-Q9VP-3WCG-8P4X Incus vulnerable to local privilege escalation through VM screenshot path

Summary Incus provides an API to retrieve VM screenshots, that API relies on the use of a temporary file for QEMU to write the screenshot to which is then picked up and sent to the user prior to deletion. As Incus uses predictable paths under /tmp for this, an attacker with local access to the...
