CVE-2025-22134

Name of the Vulnerable Software and Affected Versions Vim versions prior to 9.1.1003

Description The issue is related to a heap-buffer overflow in Vim when switching to other buffers using the :all command while visual mode is still active. This occurs because Vim does not properly end visual mode, potentially allowing access beyond the end of a line in a buffer. The impact is considered medium, as the user must have switched on visual mode when executing the :all ex command.

Recommendations For versions prior to 9.1.1003, update to Vim patch v9.1.1003 or later to fix the bug. As a temporary workaround, consider avoiding the use of the :all command while visual mode is active until the patch is applied.
