CVE-2026-50560

A flaw was found in Netty, a network application framework. A remote attacker can exploit a vulnerability in the HTTP/2 Hypertext Transfer Protocol version 2 maximum header size handling. By sending a specific SETTINGSMAXHEADERLISTSIZE setting, an attacker can cause Netty to produce an exception...

CVE-2026-50020

A flaw was found in Netty. The HttpObjectDecoder component, which processes incoming HTTP requests, incorrectly skips certain control characters and whitespace before reading the first request line. This behavior, which goes beyond standard HTTP protocol requirements, can lead to request-boundary...

CVE-2026-47244

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a large number of HTTP/2 stream requests to a Netty HTTP/2 server. If the server does not explicitly limit concurrent streams, it can lead to the allocation of numerous long-liv...

CVE-2026-45536

A flaw was found in Netty, a network application framework. A local attacker could exploit a vulnerability in the nettyunixsocketrecvFd function when handling SCMRIGHTS messages in Epoll or KQueue DomainSocketChannel with DomainSocketReadMode.FILEDESCRIPTORS enabled. Incorrect handling of file...

CVE-2026-50011

A flaw was found in Netty, a network application framework. The RedisArrayAggregator component pre-allocates memory based on the declared element count in a Redis array header. A remote attacker can exploit this by sending a small, malicious Redis array header that claims a huge initial capacity,...

CVE-2026-50010

A flaw was found in Netty, a network application framework. This vulnerability allows a remote attacker to bypass hostname verification due to improper handling of user-supplied trust managers. When a client is configured with a plain X.509 Trust Manager X509TrustManager, it fails to perform...

CVE-2026-48006

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by repeatedly closing Redis pipeline connections before a Redis array aggregate completes. This leads to a permanent leak of direct-memory buffers, which prevents memory chunks from being returned to the share...

CVE-2026-47691

A flaw was found in Netty's DnsResolveContext. An attacker controlling an authoritative name server for a subdomain can exploit this vulnerability by providing crafted NS records that are insufficiently validated. This allows the attacker to poison the DNS cache for parent domains, bypassing...

CVE-2026-46340

A flaw was found in netty-transport-sctp. A remote attacker can exploit this vulnerability by sending specially crafted, non-complete Stream Control Transmission Protocol SCTP message fragments. This can lead to unbounded memory growth within the application, causing a Denial of Service DoS...

CVE-2026-45674

A flaw was found in Netty's DnsResolveContext. This vulnerability allows a remote attacker to achieve information disclosure or data manipulation by crafting malicious DNS responses. The flaw occurs because the DnsResolveContext fails to validate the origin bailiwick of CNAME records in DNS...

CVE-2026-45416

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...

CVE-2026-44890

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by sending specially crafted Redis payloads across multiple connections without proper termination. This can exhaust the server's direct memory pool, leading to a Denial of Service DoS condition where legitima...

CVE-2026-44250

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by sending a specially crafted Redis payload containing deeply nested arrays. This action forces the server to allocate a large number of state objects and collections, leading to memory exhaustion...
