The bug `KASAN: slab-use-after-free in qxl_mode_dumb_create` is reproduced
on 5.10 stable branch.

The problem has been fixed by the following patch which can be cleanly
applied to 5.10. The fix is already included in all stable branches
starting from 5.15.

Link to the "failed to apply to 5.10" report [1].
