Fix Recommendation

Configure RHEL 10 to enable hardening for the BPF JIT compiler.

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

$ sudo vi /etc/sysctl.d/99-net_core-bpf_jit_harden.conf

Add the following line to the file:

net.core.bpf_jit_harden = 2

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

$ sudo sysctl --system

Check Contents

Verify RHEL 10 enables hardening for the BPF JIT compiler.

Check the status of the "net.core.bpf_jit_harden" parameter with the following command:

$ sudo sysctl net.core.bpf_jit_harden
net.core.bpf_jit_harden = 2

If "net.core.bpf_jit_harden" is not equal to "2" or is missing, this is a finding.
