Updated: 11 October 2026 · Applies to: cPanel & WHM 138 (root)
If WHM shows an old kernel version after a kernel update, cPanel's cached system information is out of date.
Fix (root)
mv /var/cpanel/sysinfo.config /root/sysinfo.config.bak /usr/local/cpanel/scripts/gensysinfo
Also make sure the server was rebooted into the new kernel: uname -r shows the running kernel.
