CVE-2026-42199: CWE-190: Integer Overflow or Wraparound in becheran grid
CVE-2026-42199 is an integer overflow vulnerability in the Rust data structure library 'becheran grid' versions 0. 17. 0 up to but not including 1. 0. 1. The overflow occurs in the Grid::expand_rows() function, which can corrupt the internal relationship between the grid's logical dimensions and its backing storage. This corruption can cause the safe API method get() to call get_unchecked() with an invalid index, leading to undefined behavior. The issue has been fixed in version 1. 0. 1.
AI Analysis
Technical Summary
The vulnerability involves an integer overflow in the expand_rows() method of the becheran grid Rust library, affecting versions from 0.17.0 to before 1.0.1. This overflow breaks the internal invariant that maintains consistency between the grid's logical size and its underlying storage. As a result, the safe get() method may internally invoke get_unchecked() with an out-of-bounds index, causing undefined behavior. This can lead to potential memory safety issues in Rust applications using the affected versions. The vulnerability is classified under CWE-190 (Integer Overflow or Wraparound).
Potential Impact
The integer overflow can cause undefined behavior due to invalid memory access when the safe API calls an unchecked method with an invalid index. While there is no direct confidentiality or integrity impact noted, the availability impact is rated high in the CVSS vector, indicating potential application crashes or instability. No known exploits are reported in the wild.
Mitigation Recommendations
This vulnerability has been patched in becheran grid version 1.0.1. Users of affected versions (>= 0.17.0 and < 1.0.1) should upgrade to version 1.0.1 or later to remediate this issue. No other mitigation or temporary workaround is indicated.
