CVE-2025-33220
CVE-2025-33220 affects NVIDIA vGPU software (Virtual GPU Manager). The issue is a heap memory access after free, potentially enabling code execution, escalation of privileges, data tampering, denial of service, or information disclosure. CVSS metrics indicate LOCAL access, LOW privileges required...
CVE-2026-23553
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-2026-23553
The Xen hypervisor contains a flaw in its context switch logic where it attempts to skip an Indirect Branch Prediction Barrier (IBPB) when a vCPU returns to a CPU where it was the previous vCPU to run. While this maintains isolation between vCPUs, it prevents the guest kernel from correctly isola...

CVE-2026-21417
Dell CloudBoost Virtual Appliance, versions prior to 19.14.0.0, contains a Plaintext Storage of Password vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Elevation of privileges...
kernel: KVM: arm64: Tear down vGIC on failed vCPU creation
A use-after-free flaw was found in KVM for arm64 in the Linux Kernel, if the kvmarchvcpucreate fails to share the vCPU page with the hypervisor. This vulnerability could even lead to a kernel information leak problem...

kernel: Linux kernel: vsock vulnerability may lead to memory corruption
A flaw was found in the Linux kernel's vsock component. This vulnerability occurs when a connect operation on an already established socket is interrupted by a signal or timeout, causing the system to mishandle the socket's state. This incorrect handling can lead to a race condition, potentially...

kernel: drm/i915: mark requests for GuC virtual engines to avoid use-after-free
A use-after-free vulnerability was found in the Linux kernel Intel i915 graphics driver's GuC virtual engine request handling. A local user with access to GPU rendering can create requests on GuC virtual engines and trap references via syncfile or dmabuf, causing fence release operations to acces...
kernel: i40e: add validation for ring_len param
A flaw was identified in the Intel “i40e” Ethernet driver in the Linux Kernel where the ringlen parameter supplied by a VF virtual function is passed unchecked to the hardware memory context. If a malicious Virtual function provides a too-large or misaligned ringlen, it may allow the device to...
