Not an issue. I only use sugar in beef rubs that need it - those with bitter elements, and that can be quite a few of my rubs for beef (unsweet cocoa, coffe, etc.) - and I routinely hit temps of over 350, even before foiling.
Sugar caramelizes at 320, burns >350 - but there is evaporation at the surface which keeps temps there lower (for a time; once surface moisture is gone all bets are off, but this does not occur with typical cooks). Because temps at the surface will hit the caramelization point eventually, if not the burn point, expect significant darkening (for me, not an issue with brisket), but not burning.
