Very low probability of exploitation
EPSS predicts the probability of exploitation in the next 30 days based on real-world threat data, complementing CVSS severity scores with actual risk assessment.
The get_disjoint_mut method in slab v0.4.10 incorrectly checked if indices were within the slab's capacity instead of its length, allowing access to uninitialized memory. This could lead to undefined behavior or potential crashes.
This has been fixed in slab v0.4.11.
Avoid using get_disjoint_mut with indices that might be beyond the slab's actual length, or upgrade to v0.4.11 or later.
