CVE-2023-50711 is a critical out-of-bounds memory access vulnerability affecting rust-vmm vmm-sys-util versions 0.5.0 through 0.11.x. The flaw resides in the FamStructWrapper::deserialize implementation, which fails to validate that the header's stored length matches the flexible array length, potentially allowing attackers to trigger out-of-bounds memory access through Rust-safe methods. With a CVSS score of 9.8 (CRITICAL), this vulnerability is remotely exploitable with low attack complexity and can lead to high impacts on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
