CVE-2026-41907: uuid: Missing buffer bounds check in v3/v5/v6 when buf is provided
(updated )
The v3(), v5(), and v6() API methods (not uuid release versions) accept external output buffers but do not reject out-of-range writes (small buf or large offset).
By contrast, v4(), v1(), and v7() API methods explicitly throw RangeError on invalid bounds.
This inconsistency allows silent partial writes into caller-provided buffers.
