CVE-2025-58150

Shadow mode tracing code uses a set of per-CPU variables to avoid cumbersome parameter passing. Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the writes was missing...

EUVD-2026-4882

In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Consider: 1 vCPU runs on CPU A, running task ...

CVE-2025-58150 x86: buffer overrun with shadow paging + tracing

Shadow mode tracing code uses a set of per-CPU variables to avoid cumbersome parameter passing. Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the writes was missing...

CVE-2025-58150

CVE-2025-58150 affects the Xen hypervisor (shadow mode tracing code) where per-CPU variables are written with guest-controlled data. The writes can exceed the destination variable, and bounding is missing, enabling memory corruption. Public advisories (XSA-477) and multiple distro updates (Fedora...

PT-2026-5172

NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager, where a malicious guest could cause heap memory access after the memory is freed. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, or...

x86: buffer overrun with shadow paging + tracing

ISSUE DESCRIPTION Shadow mode tracing code uses a set of per-CPU variables to avoid cumbersome parameter passing. Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the writes was missing. IMPAC...

x86: incomplete IBPB for vCPU isolation

ISSUE DESCRIPTION In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Consider: 1 vCPU runs on CP...
