There no universal standard, but the kernel is usually found in the /boot directory.

5Using cat /proc/cmdline is a better method because if you use the uname -r you will not be able to tell the difference between that kernel image or a rescue image built from the same kernel version. – None – 2015-11-15T20:16:02.953

1You can use uname -r to find out the version you're running and then look for a file in /boot with that name. You can also use cat /proc/cmdline to find the kernel path, but note that this path is relative to the root image at boot time, so / likely means /boot/ in the running system. – David Schwartz – 2012-08-17T08:17:51.077

1The path that the kernel reports that it was loaded from is relative to the root as it was at the time the kernel was loaded. That's probably called /boot by the time the system is fully loaded. (After the kernel has been booted, the root is "pivoted" to the normal root and the boot time root is usually called /boot in the run-time filesystem.) – David Schwartz – 2012-08-17T08:23:45.460
