The Photon operating system must restrict core dumps.


Finding ID Version Rule ID IA Controls Severity

By enabling the fs.suid_dumpable kernel parameter, core dumps are not generated for setuid or otherwise protected/tainted binaries. This prevents users from potentially accessing core dumps with privileged information they would otherwise not have access to read.

Check Text ( C-62644r933771_chk )
At the command line, run the following command to verify core dumps are restricted:

# /sbin/sysctl fs.suid_dumpable

Example result:

fs.suid_dumpable = 0

If the "fs.suid_dumpable" kernel parameter is not set to "0", this is a finding.

Navigate to and open:


Add or update the following line:

fs.suid_dumpable = 0

At the command line, run the following command to load the new configuration:
