CVE-2026-28419

6.6 mediumEPSS 0.2%

Medium (6.6) in vim vim. EPSS 0.2% chance of exploitation in the next 30 days.

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.
