WebMaze: Defending against LLM-Powered Web Scanners with Functionality-Coupled Deception

Large language models LLMs have enabled more effective vulnerability scanning of web applications. However, these capabilities also make it significantly easier for attackers to automate cyberattacks on the web. In this work, we investigate how to divert malicious LLM-based web scanning, with...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.6.158, 6.12.111, and 6.18.53. This vulnerability arises because kfddbgtrapenable fails to revert enabled debug traps and related states when copying runtimeinfo into user space; as a result, trap states become inconsistent and...

CVE-2026-98713

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for ARM64. A malicious guest user can cause a denial of service DoS on the host system by executing specific instructions on hardware lacking Fine-Grained Traps FGT support. Because trap configurations were improper...

CVE-2026-98546

A flaw was found in the Linux kernel's ARM64 architecture support. When user-space access to performance monitoring counters is enabled, write traps for a write-only performance register are improperly configured during hypervisor initialization. A local user can exploit this vulnerability by...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.6 contains security vulnerabilities. These vulnerabilities arise from the lack of initializing the .num member before accessing the.hws array. This can lead to out-of-bounds array indexing or trigger traps...

vm2: Incomplete nodejs.* symbol filtering lets sandbox override host WebStream state checks

Summary vm2 current head v3.11.5, commit 7a1f5100b96f48d34e0fe104ab37c0acc5944f92 still exposes registered Node.js internal symbols from host WebStream prototypes to sandbox code. The prior nodejs. symbol hardening blocks Symbol.for'nodejs.' at the source, but the extraction filters and bridge...
