CVE-2022-3647

Crash-report truncation via invalid pointer backtrace

Published Oct 21, 2022 · Updated Apr 15, 2025

Crash-reporting failure in Redis 6.2.0 through 6.2.7 and 7.0.0 through 7.0.5 allows local users to truncate crash diagnostics. In sigsegvHandler in src/debug.c, backtrace dereferences the invalid instruction pointer that caused the original crash, triggering a second crash before the full report is logged. The path is reachable only after Redis has already crashed, and Redis disputes any additional service interruption beyond loss of diagnostic output.
