| Doc Text: |
A flaw was found in slab. The `get_disjoint_mut` method incorrectly validates index boundaries against the slab's capacity rather than its length, enabling a local attacker to access uninitialized memory. This memory access occurs when requesting disjoint mutable references within the slab. Consequently, this can lead to information disclosure.
