Title

The kernel core dump data directory must be owned by root. (Cat III impact)

Discussion

Kernel core dumps may contain the full contents of system memory at the time of the crash. As the system memory may contain sensitive information, it must be protected accordingly. If the kernel core dump data directory is not owned by root, the core dumps contained in the directory may be subject to unauthorized access.

Check Content

Check the ownership of the kernel core dump data directory. # ls -ld /var/crash OR # ls -ld `grep DUMPADM_SAVDIR /etc/dumpadm.conf | cut -d= -f2` If the kernel core dump data directory is not owned by root, this is a finding.

Fix Text

Change the owner of the kernel core dump data directory to root. # chown root /var/crash
