CVE-2022-0368Public exploit

Local memory disclosure via stale Visual position

Published Jan 26, 2022 · Updated Aug 2, 2024

Out-of-bounds read in Vim before 8.2.4217 allows local users to disclose process memory through crafted editing commands. Vim's u_undo_end() leaves the Visual selection position beyond a shortened line after undo instead of validating it against the current buffer. Exploitation requires a user to execute the attacker-supplied command sequence in an affected editor process.
