CVE-2022-3099Public exploit

Application crash via invalid for-command line number

Published Sep 3, 2022 · Updated Nov 3, 2025

Use-after-free in Vim before 9.0.0360 allows local users to crash the editor by opening a crafted file containing an invalid :for line number. In do_cmdline() in src/ex_docmd.c, Vim performs breakpoint lookup after the invalid line number leaves no corresponding stored command line, accessing freed line-state memory. The attack requires user interaction with the crafted file, and the upstream reproducer demonstrates an application crash.
