High [CVE-2026-55833] Denial of Service via SPDY header decompression amplification
Netty is a network application framework for development of protocol servers and clients. Prior to 4.1.136.Final and 4.2.16.Final, Netty SPDY header decoding continues inflating zlib-compressed header blocks after the raw header parser has exceeded `maxHeaderSize` and marked the frame truncated in `SpdyFrameCodec`, allowing a remote peer to send a small compressed `HEADERS` block that expands into much larger raw header data and causes compression-amplified CPU and allocation churn. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to excessive CPU usage and memory allocation. This can result in a denial of service (DoS) due to resource exhaustion. This is an Important denial of service vulnerability in Netty's SPDY header decoding. A remote, unauthenticated attacker can send a small, compressed SPDY header block that, during decompression, expands significantly beyond configured limits. This leads to excessive CPU and memory consumption, potentially causing resource exhaustion and service unavailability in affected Red Hat products that utilize Netty with SPDY. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-409.
