CVE-2026-28419: Vim

Medium severity, CVSS 6.6. 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.

Affected products

• Vim Vim: before 9.2.0075 (fixed in 9.2.0075)
