Last modified Jun 17, 2026

CVE-2017-16539 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP.. EPSS estimates a 1.85% chance of exploitation in the next 30 days.
