CVE-2026-42199: CWE-190: Integer Overflow or Wraparound in becheran grid
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.
AI Analysis
Technical Summary
The becheran grid Rust library versions from 0.17.0 to before 1.0.1 contain an integer overflow vulnerability in the Grid::expand_rows() method. This overflow breaks the internal invariant that maintains consistency between the grid's logical dimensions and its underlying storage. When this invariant is violated, the safe method get() may internally invoke get_unchecked() with an invalid index, resulting in undefined behavior. This vulnerability is tracked as CVE-2026-42199 with a CVSS 3.1 base score of 6.2 (medium severity). The issue has been patched in version 1.0.1.
Potential Impact
Exploitation of this integer overflow can lead to undefined behavior due to invalid memory access when using the safe get() API. While there is no direct confidentiality or integrity impact reported, the vulnerability causes availability impact (crashes or unstable behavior). There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade to becheran grid version 1.0.1 or later, where this integer overflow vulnerability has been patched. No other mitigation or temporary workaround is indicated.
