Grid: Integer Overflow in Grid::expand_rows Leads to Safe-API Undefined Behavior

Published May 8, 2026 CVSS 3.1 · 6.2 Medium EPSS < 1% KEV · Not listed
Description
Grid is a data structure grid for rust. From version 0.17.0 to before version 1.0.1, an integer overflow in Grid::expand_rows() can corrupt the relationship between the grid’s logical dimensions and its backing storage. After the internal invariant is broken, the safe API get() may invoke get_unchecked() with an invalid index, resulting in Undefined Behavior. This issue has been patched in version 1.0.1.
