Isolation Failure from Shared Storage: Characterizing and Exploiting Page-Cache SCA Leakage across Containers and VMs

Modern cloud platforms increasingly combine strong software isolation mechanisms with shared hardware resources to improve performance and resource efficiency. Conventional containers do this by sharing the host kernel directly, whereas sandboxed runtimes e.g., gVisor and VM-based runtimes e.g.,...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected role

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM x86 shadow paging mechanism. This vulnerability occurs when a host page directory entry PDE mapping is changed from within the guest, leading to an unexpected role mismatch in shadow paging. This mismatch can cause a...

VulnCheck KEV: CVE-2026-46442

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, POST /api/v1/node-custom-function lacks route-level authorization, allowing any authenticated user or API key to submit arbitrary JavaScript to the Custom JS Function node. When...
