CVE-2026-42577
HIGH7.5EPSS 0.05%Netty epoll transport denial of service via RST on half-closed TCP connection
發布日:2026/5/6修改日:2026/5/14
描述
Netty is an asynchronous, event-driven network application framework. From 4.2.0.Final to 4.2.13.Final , Netty's epoll transport fails to detect and close TCP connections that receive a RST after being half-closed, leading to stale channels that are never cleaned up and, in some code paths, a 100% CPU busy-loop in the event loop thread. This vulnerability is fixed in 4.2.13.Final.
