Doc Text:
A heap use-after-free vulnerability was found in vim's movemark() function of the src/mark.c file. This issue occurs because vim uses freed memory when 'autocmd' changes the mark. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a heap use-after-free that causes an application to crash, possibly executing code and corrupting memory.
