CVE-2022-23563

Local data exposure and corruption via temporary-path race

Published Feb 4, 2022 · Updated Apr 23, 2025

TOCTOU races in Google TensorFlow before 2.5.3, 2.6.0 through 2.6.2, and 2.7.0 allow local users to read or alter temporary data. Multiple utilities call tempfile.mktemp and later create a file or directory at the returned path, leaving a window for another process to claim that path first. Exploitation requires local access and winning the race; successful path substitution exposes or corrupts data handled by the affected operation.
