Cross-Scale Persistence Analysis of EM Side-Channels for Reference-Free Detection of Always-On Hardware Trojans

Always-on hardware Trojans pose a serious challenge to integrated circuit trust, as they remain active during normal operation and are difficult to detect in post-deployment settings without trusted golden references. This paper presents a reference-free detection framework based on cross-scale...

LLM Jailbreak Detection for (Almost) Free!

Large language models LLMs enhance security through alignment when widely used, but remain susceptible to jailbreak attacks capable of producing inappropriate content. Jailbreak detection methods show promise in mitigating jailbreak attacks through the assistance of other models or multiple model...

CVE-2022-49127

In the Linux kernel, the following vulnerability has been resolved: reftracker: implement use-after-free detection Whenever reftrackerdirinit is called, mark the struct reftrackerdir as dead. Test the dead status from reftrackeralloc and reftrackerfree This should detect buggy devput/devhold...

CVE-2022-49127 ref_tracker: implement use-after-free detection

In the Linux kernel, the following vulnerability has been resolved: reftracker: implement use-after-free detection Whenever reftrackerdirinit is called, mark the struct reftrackerdir as dead. Test the dead status from reftrackeralloc and reftrackerfree This should detect buggy devput/devhold...

CVE-2022-49127

CVE-2022-49127 is a Linux kernel vulnerability fix where the ref_tracker use-after-free detection was added. The patch marks the ref_tracker_dir as dead during ref_tracker_dir_init() and checks this dead status from ref_tracker_alloc() and ref_tracker_free(), aiming to detect buggy dev_put()/dev_...
