Where is vmlinux file for crash dump

I have setup kdump to help me diagnose a kernel crash (per redhat docs). I've gotten as far as creating the dump file, and now want to examine the crash dump file. The instructions say to execute (for example): crash /usr/lib/debug/lib/modules/4.18.0-5.el8.x86_64/vmlinux /var/crash/127.0.0.1-2018-10-06-14:05:33/vmcore But I don't have a vmlinux file. I looked int the directory matching my kernel **( /usr/lib/modules/5.14.0-427.37.1.el9_4.x86_64+debug)** and it contains the content shown below. But no vmlinux file! I have a vmlinuz but the crash program didn't like it. Where do I find this vmlinux file, or do I have to create it? lrwxrwxrwx. 1 root root 51 Sep 24 17:25 build -> /usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64+debug -rw-r--r--. 1 root root 224287 Sep 24 17:25 config drwxr-xr-x. 14 root root 156 Oct 5 08:18 kernel -rw-r--r--. 1 root root 879087 Oct 5 08:19 modules.alias -rw-r--r--. 1 root root 834103 Oct 5 08:19 modules.alias.bin -rw-r--r--. 1 root root 461 Sep 24 17:25 modules.block -rw-r--r--. 1 root root 9236 Sep 24 17:25 modules.builtin -rw-r--r--. 1 root root 0 Oct 5 08:19 modules.builtin.alias.bin -rw-r--r--. 1 root root 11585 Oct 5 08:19 modules.builtin.bin -rw-r--r--. 1 root root 75121 Sep 24 17:25 modules.builtin.modinfo -rw-r--r--. 1 root root 307245 Oct 5 08:19 modules.dep -rw-r--r--. 1 root root 400740 Oct 5 08:19 modules.dep.bin -rw-r--r--. 1 root root 387 Oct 5 08:19 modules.devname -rw-r--r--. 1 root root 155 Sep 24 17:25 modules.drm -rw-r--r--. 1 root root 20 Sep 24 17:25 modules.modesetting -rw-r--r--. 1 root root 1648 Sep 24 17:25 modules.networking -rw-r--r--. 1 root root 93145 Sep 24 17:25 modules.order -rw-r--r--. 1 root root 862 Oct 5 08:19 modules.softdep -rw-r--r--. 1 root root 499371 Oct 5 08:19 modules.symbols -rw-r--r--. 1 root root 591632 Oct 5 08:19 modules.symbols.bin lrwxrwxrwx. 1 root root 5 Sep 24 17:25 source -> build -rw-r--r--. 1 root root 404401 Sep 24 17:25 symvers.gz -rw-------. 1 root root 9446409 Sep 24 17:25 System.map drwxr-xr-x. 2 root root 6 Sep 24 17:24 systemtap drwxr-xr-x. 2 root root 6 Sep 24 17:25 updates drwxr-xr-x. 2 root root 40 Oct 5 08:18 vdso -rwxr-xr-x. 1 root root 27304248 Sep 24 17:25 vmlinuz drwxr-xr-x. 2 root root 6 Oct 5 08:19 weak-updates
