The vulnerability allows attackers to flood the server with RST_STREAM frames by sending malformed HTTP/2 control frames. The fix consists of two parts: (1) routing all RST_STREAM writes through the encoder chain via encoder().writeRstStream(), and (2) introducing Http2MaxRstFrameLimitEncoder that tracks and rate-limits outgoing RST frames, closing the connection when the threshold is exceeded. Both components are present and enabled by default for servers (200 RST frames per 30-second window). The fix was authored by upstream Netty maintainer Norman Maurer (norman_maurer@apple.com) in commit 009bd17b38 (August 2025) and was included in the upstream 4.1.128.Final release (October 2025), which TuxCare onboarded on October 1, 2026.
