CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers and security researchers who need fast privilege escalation attack paths during engagements will get immediate value from Linux Exploit Suggester 2; it cuts the reconnaissance phase by matching kernel versions directly to exploitable CVEs without manual database hunting. The 1,960 GitHub stars and active maintenance mean the exploit signatures stay current enough for most standard Linux distributions. Skip this if you're looking for a full post-exploitation framework or something that handles non-kernel vulnerabilities; this tool is deliberately narrow, which is exactly why it's fast.
Penetration testers and red teamers auditing Linux infrastructure should run SUDO_KILLER during privilege escalation testing; it methodically hunts misconfigurations in sudo rules that most manual reviews miss. The tool has 2,447 GitHub stars and costs nothing, making it a zero-friction addition to any Linux assessment toolkit. Skip this if you're looking for post-exploitation persistence or lateral movement coverage; SUDO_KILLER is narrowly focused on the escalation vector itself, which is exactly why it's effective at that one job.
