[FOOS Tool] Z-Privesc – 100% privesc detection in 2.65s for 5.4+ Linux kernel
Source Reddit Cybersecurity
Discussion
Z-Privesc is a security tool designed for privilege escalation detection on Linux kernels version 5.4 and above. It is a static C binary that performs 17 probes and provides deterministic verdicts with high accuracy on a ground-truth corpus. The tool claims to outperform other similar tools like LinPEAS and Lynis, requires no dependencies, and is released under the MIT license.

Impact
This entry describes a security tool for detection rather than a vulnerability or exploit. It does not represent a direct threat but rather a defensive capability to identify privilege escalation risks on Linux systems. There is no indication of exploitation or vulnerability associated with this tool.
Defensive guidance
Not applicable as this is a detection tool, not a vulnerability. No patch or remediation is required. Security teams may consider using this tool to enhance their privilege escalation detection capabilities on Linux systems with kernel 5.4 or later.
Summary
Z-Privesc is a Linux privilege escalation detection tool targeting kernel versions 5.4 and later. It operates as a static C binary performing multiple probes to detect potential privilege escalation vectors with deterministic results. The tool has been tested on a ground-truth corpus with perfect accuracy (37/37) and is claimed to be faster and more accurate than comparable tools such as LinPEAS and Lynis. It is open source and dependency-free, facilitating easy deployment.
