  MAINTAINERS: update parallels tree location (2026-07-27 14:42:24 +0200)

----------------------------------------------------------------
Parallels block driver patches

- fix a reachable assert()/process abort on a crafted image with an
  inconsistent BAT vs. advertised disk size (GitLab #3804)
- fix related integer overflows capping the format's usable catalog
  size below its documented maximum
- reject BAT entries pointing outside the data area in either
  direction
- harden the dirty-bitmap extension loader against a reachable
  abort and an unsafe allocator
