Official Description
Vim is an open source, command line text editor. Prior to version 9.2.0078, a stack-buffer-overflow occurs in `build_stl_str_hl()` when rendering a statusline with a multi-byte fill character on a very wide terminal. Version 9.2.0078 patches the issue.

CVE-2026-28422 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
