CVE-2026-28419
February 27, 2026
Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue.
