That's not really Arabic,
Double Harmonic Minor is just a western invention that sounds vaguely "exotic".
Love Whitesnake, but I can't stand hearing stuff in that kind of tonality anymore. Too hokey. I mean, the first time I heard it at 16 it was like, "What is this?", but every time hearing anything with the double harmonic/byzantine/hungarian type shit these days it loses appeal exponentially.
I made the mistake of calling it Arabic to actual Arabic friends years and years ago. It's basically like approaching a Chinese person and being like, "I love authentic Chinese food like Panda Buffet." or telling a hispanic how much you appreciate their fine traditional Taco Bell cuisine.
"Standard diatonic western tonality with a flat second, raised/augmented third, and either a major or minor 7th meant to vaguely emulate exotic sounds" is the correct term. Trust me on that one. It can occasionally work in older shit, like Gates of Babylon or Scorpions late 70s/early 80s era, but the novelty wore off decades ago. Even if it wasn't already overused in more "classic" metal, extreme metal used it for like 75% of songs from 2004-2008.
The other stuff on the new Whitesnake is cool, but anything with the double harmonic thing going elicits a re-action of "Gates of Babylon was already written decades ago dude" with me.
