CVE-2026-28419

A flaw was found in Vim, an open-source command-line text editor. This vulnerability, a heap-based buffer underflow, occurs when Vim processes a specially crafted Emacs-style tags file. If a malicious file with a delimiter at the start of a line is opened, Vim attempts to read memory outside its designated area. This could lead to the disclosure of sensitive information or cause the application to crash, resulting in a denial of service.
