CVE-2022-0685 Use of Out-of-range Pointer Offset in GitHub repository vim/vim prior to 8.2.4418.

You may have been encountering the following issue while working on your projects or Git repos: When you are updating a file in GitHub with vim, you may notice that the last line of the file ends up in a different location. This might seem like a minor issue, but it can cause major issues in the long run. What happens is, when you update a file in GitHub with vim, GitHub will update the pointer to the next location, which may not be where the file actually resides.
This leads to confusion between the pointer and the location of the file in the Git repo. As a result, when you run commands such as git status or git commit, you may be getting different results than what you expected. To resolve this issue, you can add the following command to your .vimrc file: vmap F5> Plug>(GitPointerOffset)Plug>(Arg1) When you are working on a file in GitHub, you can press F5> to update the pointer to the next location. This will cause the pointer to point to the location of the file in your Git repo, and this will avoid any confusion in the next commit.

If you are unsure how to locate the origin of the problem, you can check the commit history to find out where this error originated.
