CVE-2026-102703
A flaw was found in Xen. When processing batched grant copy operations used for memory sharing between virtual machines, the hypervisor caches internal validation data but fails to properly re-validate it when frame numbers and grant references are intermixed. A malicious guest domain can exploit...
CVE-2021-3656-Demo
CVE-2021-3656: This issue is caused by missing validation of the the virtext VMCB field and allows a malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and VLS Virtual VMLOAD/VMSAVE for the L2 guest. Under these circumstances, the L2 guest is able to run VMLOAD/VMSAVE unintercepted, and...
Information Exposure
Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Information Exposure via the Buffer pool. An attacker can access and manipulate host memory by leveraging sandboxed code to acquire ArrayBuffers from...

Astra Linux – Vulnerability in Linux
A flaw was discovered in the KVM’s AMD code, which handles SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the “virtext” field, this issue could all...
Security Bulletin: This Power System update is being released to address CVE-2026-16933
Summary Power Systems Firmware is affected by a vulnerability in the interface between the BMC/FSP and the host system. An attacker with service account or root access to the BMC/FSP can read and write arbitrary regions of host system memory, giving full control over the host system and all hoste...
CVE-2026-64286
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architecture. The flushhypvcpu function, responsible for copying the host virtual CPU vCPU context, does not properly clear a specific internal pointer hyprunningvcpu. This oversight allows a host to provide a value...
USN-8550-1 libslirp vulnerability
It was discovered that libslirp incorrectly handled TCP urgent data. A privileged attacker inside a guest VM could possibly use this issue to obtain sensitive information from the host process memory...

GHSA-XX5W-CVP6-JV83 Wasmtime with Winch compiler backend on aarch64 may allow a sandbox-escaping memory access
Impact Wasmtime with its Winch baseline non-default compiler backend may allow properly constructed guest Wasm to access host memory outside of its linear-memory sandbox. This vulnerability requires use of the Winch compiler -Ccompiler=winch. By default, Wasmtime uses its Cranelift backend, not...
CVE-2026-34987
Wasmtime is a runtime for WebAssembly. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime with its Winch baseline non-default compiler backend may allow properly constructed guest Wasm to access host memory outside of its linear-memory sandbox. This vulnerability requires use of the Winch...
CVE-2026-34971
Wasmtime is a runtime for WebAssembly. From 32.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Cranelift compilation backend contains a bug on aarch64 when performing a certain shape of heap accesses which means that the wrong address is accessed. When combined with explicit bounds checks a...
CVE-2026-35186 Wasmtime has an improperly masked return value from `table.grow` with Winch compiler backend
Wasmtime is a runtime for WebAssembly. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Winch compiler backend contains a bug where translating the table.grow operator causes the result to be incorrectly typed. For 32-bit tables this means that the result of the operator, internally i...
