Description
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.

ℹ️ Check
The root role is required. This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this check applies. Determine the location of the system dump directory. # dumpadm \| grep directory Check the ownership of the kernel core dump data directory. # ls -ld [savecore directory] If the kernel core dump data directory is not owned by root, this is a finding. In Solaris 11, /var/crash is linked to /var/share/crash.
