ksj1230 opened a new issue, #9904: URL: https://github.com/apache/arrow-rs/issues/9904
## Description This issue was previously reported privately and is now being disclosed following coordination with maintainers. `repeat_slice_n_times()` computes repeated byte length using unchecked arithmetic. When the multiplication overflows, capacity checks may be bypassed, leading to insufficient allocation. This can result in a potential out-of-bounds write via safe Rust APIs. ## Fix See PR #9819 Reported by Sungjin Kim (@ksj1230) -- This is an automated message from the Apache Git Service.
