kernel: ext4: fix use-after-free in ext4_orphan_cleanup

A use-after-free vulnerability was found in the ext4 filesystem's orphan inode cleanup routine in the Linux kernel. When ext4inodeattachjinode fails with -ENOMEM during orphan cleanup at mount time, the error is not properly propagated. The inode is freed via iput, but the orphan list still...

Internet Malware Propagation: Dynamics and Control through SEIRV Epidemic Model with Relapse and Intervention

Malware attacks in today's vast digital ecosystem pose a serious threat. Understanding malware propagation dynamics and designing effective control strategies are therefore essential. In this work, we propose a generic SEIRV model formulated using ordinary differential equations to study malware...

VEcho: A Paradigm Shift from Vulnerability Verification to Proactive Discovery with Large Language Models

Static Application Security Testing SAST tools often suffer from high false positive rates, leading to alert fatigue that consumes valuable auditing resources. Recent efforts leveraging Large Language Models LLMs as filters offer limited improvements; however, these methods treat LLMs as passive,...

Agents of Chaos

We report an exploratory red-teaming study of autonomous language-model-powered agents deployed in a live laboratory environment with persistent memory, email accounts, Discord access, file systems, and shell execution. Over a two-week period, twenty AI researchers interacted with the agents unde...

How Security Tool Misuse Is Reshaping Cloud Compromise

Key Takeaways Legitimate secret-scanning tools such as TruffleHog have been operationalized in real-world cloud attack campaigns. Attack progression commonly follows a repeatable sequence: credential discovery, live validation, permission enumeration, and data access. Exposed long-lived access ke...
