CVE-2022-35922 is a high-severity out-of-memory (OOM) vulnerability affecting Rust-WebSocket versions prior to 0.26.5, specifically its synchronous implementation. An unauthenticated attacker can trigger a process abort by sending a crafted WebSocket dataframe with an excessively large declared size, causing the application to attempt an oversized memory allocation. This results in a denial of service (DoS) for affected clients or servers. While the CVSS score is 7.5 (High), indicating a network-based attack with low complexity and high availability impact, there is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability. Organizations using affected versions are advised to upgrade to 0.26.5 or implement external traffic filtering.
