In `@buildroot-external/configs/generic_aarch64_defconfig` at line 21, The kernel
version string is incorrect: update the BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE
setting from "6.18.26" to the released "6.18.25" so the build uses the actual
LTS kernel; locate the BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE line in the config
and replace the value accordingly.
