CVE-2025-55159
Description
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.
Mitigation
To mitigate this flaw avoid using get_disjoint_mut with indices that might be beyond the slab's actual length
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
