Olivier Fourdan 36f53145e4 xwayland: Avoid NULL pointer dereference in damage_report() ... Commit 34934c37d6 restored calling register_damage() in xwl_realize_window() before ensure_surface_for_window(). However if register_damage() succeeds and ensure_surface_for_window() returns NULL, it would exit without "unregistering" the damage hook. The X11 window, however, may still get damages reports, in which case xwl_window_from_window() would return NULL, causing a NULL pointer dereference in damage_report(). To avoid the issue, make sure we unregister the damage report if ensure_surface_for_window() has failed, and add an early exit in damage_report() if xwl_window is NULL. v2: unregister_damage() unconditionally if ensure_surface_for_window() failed (Michel Dänzer) Fixes: commit 34934c37d6 ("revert: register damage before ensure_surface_for_window") Closes: https://gitlab.freedesktop.org/xorg/xserver/-/work_items/1886 Signed-off-by: Olivier Fourdan <ofourdan@redhat.com> Part-of: <https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/2190>		2026-04-24 07:16:12 +00:00
