Описание
Vim is an open source, command line text editor. In versions from 9.1.1231 to before 9.1.1406, when processing nested tuples during Vim9 script import operations, an error during evaluation can trigger a double-free in Vim’s internal typed value (typval_T) management. Specifically, the clear_tv() function may attempt to free memory that has already been deallocated, due to improper lifetime handling in the handle_import / ex_import code paths. The vulnerability can only be triggered if a user explicitly opens and executes a specially crafted Vim script. This issue has been patched in version 9.1.1406.
A double-free vulnerability was found in Vim. This flaw allows an attacker to trick a user into processing a specially crafted file to trigger the double-free, causing the application to crash.
Отчет
Red Hat Product Security has rated this issue as having a Low security impact because the user has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it. For additional information, refer to the Issue Severity Classification [1] and Red Hat Enterprise Linux Life Cycle & Updates Policy.

Меры по смягчению последствий
Do not run untrusted vim scripts as it's not recommended.
