Scientific Linux Security Update : kernel on SL6.x i386/x86_64 (20180508) (Meltdown)

Critical Nessus Plugin ID 109643

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 8.9
