CWE ID 787


CVE-2023-50711 is a vulnerability affecting the vmm-sys-util module, specifically versions 0.5.0 to 0.12.0. The issue lies in the FamStructWrapper::deserialize implementation, which can result in out-of-bounds memory accesses. The deserialization process fails to verify that the length stored in the header matches the flexible array length, potentially allowing for unauthorized memory access through Rust-safe methods. This vulnerability has been remediated in version 0.12.0 by implementing a check to ensure equal lengths of compared flexible arrays and restricting header length modification to Rust-unsafe code. The potential danger posed to an organization is medium, with a base severity score of 5.7 and an impact score of 2.7 according to CVSS 3.1 metrics.
