CVE-2026-28421: Vim

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

Vim is an open source, command line text editor. Versions prior to 9.2.0077 have a heap-buffer-overflow and a segmentation fault (SEGV) exist in Vim's swap file recovery logic. Both are caused by unvalidated fields read from crafted pointer blocks within a swap file. Version 9.2.0077 fixes the issue.

Affected products

• Vim Vim: before 9.2.0077 (fixed in 9.2.0077)
