The
from i32 column major order method can create inconsistent internal
state. When labels length and n items mismatch, n clusterings becomes
labels.len() / n items (truncated), but subsequent calls to label() use
indices that exceed the internal data bounds, causing a buffer overflow.For example,
Clusterings::from i32 column major order(&[1,2,3,4,5], 3)
creates clusterings with n clusterings = 5/3 = 1. Then
clusterings.label(1, 0) accesses index 1*3 = 3, but only 3 elements
exist (indices 0,1,2), causing out-of-bounds access.This can be triggered through safe public APIs —
from i32 column major order() and label() — with no unsafe required
from the caller. Found an issue in the description? Have something to add? Feel free to write us 👾
