CVE-2024-47814: use-after-free when closing buffers in Vim

• Severity: medium (CVSS 4.7 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-10-07 · updated 2026-06-17
• Weakness: CWE-416

Description

Vim is an open source, command line text editor. A use-after-free was found in Vim < 9.1.0764. When closing a buffer (visible in a window) a BufWinLeave auto command can cause an use-after-free if this auto command happens to re-open the same buffer in a new split window. Impact is low since the user must have intentionally set up such a strange auto command and run some buffer unload commands. However this may lead to a crash. This issue has been addressed in version 9.1.0764 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Affected products

• NetApp Bootstrap Os: all versions
• vim/vim: before 9.1.0764 — fixed in 9.1.0764

How to fix

Upgrade to a fixed version: vim/vim 9.1.0764. Check the vendor advisory for mitigations.
