Vim 9.1.1231-9.1.1400 - Use-After-Free in Tuple Reference Management
Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1400, When processing nested tuples in Vim script, an error during evaluation can trigger a use-after-free in Vim’s internal tuple reference management.
