NewCVE-2025-55159 (opens in a new tab)How to fix?
Upgrade slab to version 0.4.11 or higher.
Overview
slab is a Pre-allocated storage for a uniform data type.
Affected versions of this package are vulnerable to Out-of-Bounds via the get_disjoint_mut function. An attacker can cause undefined behavior or potential crashes by accessing memory outside the initialized bounds.
Workaround
This vulnerability can be mitigated by avoiding the use of get_disjoint_mut with indices that may exceed the actual length of the storage.
