Fix Recommendation

Configure RHEL 10 to prevent privilege escalation through the kernel by disabling access to the bpf system call.

Create the drop-in file if it does not already exist:

$ sudo vi /etc/sysctl.d/99-kernel_unprivileged_bpf_disabled

Add the following line to the file:

kernel.unprivileged_bpf_disabled = 1

Reload settings from all system configuration files with the following command:

$ sudo sysctl --system

Check Contents

Verify RHEL 10 prevents privilege escalation through the kernel by disabling access to the bpf system call.

Check the status of the "kernel.unprivileged_bpf_disabled" kernel parameter with the following command:

$ sysctl kernel.unprivileged_bpf_disabled
kernel.unprivileged_bpf_disabled = 1

If "kernel.unprivileged_bpf_disabled" is not set to "1" or is missing, this is a finding.
