The Memcache binary protocol codec incorrectly reads `keyLength` and `extrasLength` as signed Java types instead of unsigned, as specified by the protocol. A malicious Memcache server can exploit this type mismatch by sending a specially crafted response. This can lead to frame desynchronization and response smuggling, where one client's data may be inadvertently exposed to another client's response stream in proxy or cache environments.","state":0,"publishedAt":"2026-09-18T10:02:36.581+00:00","modifiedAt":"2026-09-25T08:28:53.009+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"netty-codec-memcache","ranges":[],"versions":[],"rawVersionEvidence":"{\n
