Apache Arrow Rust: Improper validation of RunEndEncoded arrays allows out of bounds reads
CVE-2026-111959 · GHSA-gqmm-qrjq-4c7h
- Affected
- crates.io arrow-data >= 33.0.0, < 57.3.2; >= 58.0.0, < 58.4.1; >= 59.0.0, < 59.3.2; >= 60.0.0, < 60.1.0
- Fixed in
- 60.1.057.3.259.3.258.4.1· Vendor fix available
- Issue
- Improper validation of RunEndEncoded arrays via `ArrayData::validate_values` can allow reading data beyond the bounds of the child values array when reading the last value via APIs such as `TypedRunArray::value`. Patched versions now properly validate the contents of RunEndEncoded arrays to prevent allowing reading out of bounds of the specified array data. Credit to Adam Korczynski of Ada Logics for reporting this and Anthropic for finding this.
Recommended action: Upgrade to 60.1.0, 59.3.2, 58.4.1 or 57.3.2 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
