Description SMASH SMASH 2023-11-20 08:37:13 UTC

When closing a window, vim may try to access already freed window structure. So before trying to access any window related variable verify that the window to be closed is still valid and if not, return.

Impact is low, since it is not very easy to make use of this and execute some payload (in particular not, without the user noticing).

The Vim project would like to thank Fabian Toepfer for reporting this issue which is now fixed in Vim patch 9.0.2106.
