Descriptions

Vim is an open source, command line text editor. A use-after-free was found in Vim < 9.1.0764. When closing a buffer (visible in a window) a BufWinLeave auto command can cause an use-after-free if this auto command happens to re-open the same buffer in a new split window. Impact is low since the user must have intentionally set up such a strange auto command and run some buffer unload commands. However this may lead to a crash. This issue has been addressed in version 9.1.0764 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

It was discovered that Vim incorrectly handled memory when closing a buffer, leading to use-after-free. If a user was tricked into opening a specially crafted file, an attacker could crash the application, leading to a denial of service.
