Integer Overflow in Grid Data Structure for Rust by Becheran
CVE-2026-42199
6.2MEDIUM
What is CVE-2026-42199?
The Grid data structure by Becheran is susceptible to an integer overflow issue in the expand_rows() function. This flaw, found in versions from 0.17.0 to before 1.0.1, can lead to a disruption of the internal relationships between logical dimensions and storage. When this invariant is violated, the safe API method get() could be forced to call get_unchecked() with an invalid index. This scenario results in Undefined Behavior, possibly compromising application stability and security. Users are advised to upgrade to version 1.0.1 to mitigate this risk.
Affected Version(s)
