In the Linux kernel, the following vulnerability has been resolved:
mm/compaction: fix UBSAN shift-out-of-bounds warning
syzkaller reported a UBSAN shift-out-of-bounds warning of (1UL << order) in isolate_freepages_block(). The bogus compound_order can be any value because it is union with flags. Add back the MAX_PAGE_ORDER check to fix the warning.
