Where to get the dSYM of current kernel

For example, I am using the macOS 10.14.6, BuildVersion: 18G95. I encounter a panic when load my kext, so I want to see which kernel function result in this panic through the backtrace info, I can get the .dSYM of my kext, but how can I get the .dSYM of the release kernel of the system of I am using?
