CVE-2025-27151

Local utility crash via unchecked file-path copy

Published May 29, 2025 · Updated May 29, 2025

Stack-based buffer overflow in Redis 7.0.0 through 8.0.1 allows local users to crash redis-check-aof via an oversized file path. The utility copies strlen(filepath) bytes into a fixed-size stack buffer without first rejecting a path that exceeds the buffer. Invocation of the bundled command-line tool is required; the published CVSS assessment limits scored impact to utility availability, while the advisory also identifies code execution as an outcome.
