CVE-2026-23323

CVE-2026-23323 concerns the Linux kernel macsmc-hwmon driver on Apple Silicon. The issue stems from two concrete bugs: (1) sensor population logic using the wrong prefix (volt- vs voltage-) and mis-assigning sensors from the voltage array to the temperature array, risking out-of-bounds access or ...

Microsoft Xbox One Hacked

It's an impressive feat, over a decade after the box was released: Since reset glitching wasn't possible, Gaasedelen thought some voltage glitching could do the trick. So, instead of tinkering with the system rest pins the hacker targeted the momentary collapse of the CPU voltage rail. This was...

Time Stepped Cyber Physical Simulation of DoS, DoD, and FDI Attacks on the IEEE 14 Bus System

Reliable grid operation depends on accurate and timely telemetry, making modern power systems vulnerable to communication layer cyberattacks. This paper evaluates how Denial of Service DoS, Denial of Data DoD, and False Data Injection FDI attacks disrupt the IEEE 14 bus system using a MATLAB only...

A PUF-Based Security Framework for Fault and Intrusion Detection

Industrial Control Systems ICS rely on sensor feedback to keep safety-critical processes within operational limits. This research presents a hardware-root-of-trust that embeds a Physically Unclonable Function PUF at the measurement layer to authenticate sensor readings. The architecture combines...
