CVE-2026-44249 (GCVE-0-2026-44249)

Vulnerability from cvelistv5 – Published: 2026-06-11 20:46 – Updated: 2026-08-10 12:05

Title

Netty has an IPv6 Subnet Filter Bypass via Incorrect Comparator Masking

Summary

Netty is a network application framework for development of protocol servers and clients. In netty-handler prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can bypass IPv6 subnet rules due to an incorrect masking operation in IpSubnetFilterRule.compareTo().

CVE-2026-44250 (GCVE-0-2026-44250)

Vulnerability from cvelistv5 – Published: 2026-06-11 20:49 – Updated: 2026-08-05 12:15

Title

Netty: Memory Exhaustion in RedisArrayAggregator due to Deeply Nested Arrays

Summary

Netty is a network application framework for development of protocol servers and clients. In netty-codec-redis prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can cause DoS by sending a crafted Redis payload with deeply nested arrays. This forces the server to allocate a massive number of state objects and collections, leading to memory exhaustion and an OutOfMemoryError. Versions 4.1.135.Final and 4.2.15.Final patch the issue.

Severity

7.5 (High)

CVE-2026-44890 (GCVE-0-2026-44890)

Vulnerability from cvelistv5 – Published: 2026-06-11 20:52 – Updated: 2026-08-05 12:14

Title

Netty has Unbounded Direct Memory Consumption in its RedisDecoder

Summary

Netty is a network application framework for development of protocol servers and clients. In netty-codec-redis prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can cause DoS by sending crafted Redis payloads across multiple connections without `\r\n`. This exhausts the server's direct memory pool (OutOfDirectMemoryError), preventing legitimate connections from being processed. Versions 4.1.135.Final and 4.2.15.Final patch the issue.

Severity

7.5 (High)

CVE-2026-44892 (GCVE-0-2026-44892)

Vulnerability from cvelistv5 – Published: 2026-06-12 05:04 – Updated: 2026-06-12 09:59

Title

Netty has a Vulnerable Default Configuration Which Leads to Denial of Service via Unbounded HTTP/3 Header Size

Summary

Netty is a network application framework for development of protocol servers and clients. Prior to version 4.2.15.Final, the default configuration of the `Http3ConnectionHandler` in the Netty HTTP/3 codec lacks an enforced maximum header size limit. When a peer does not explicitly specify `HTTP3_SETTINGS_MAX_FIELD_SECTION_SIZE`, the implementation defaults to an unbounded limit. This insecure default configuration allows a malicious client or server to send an enormous number of headers, leading to a memory exhaustion Denial of Service via an `OutOfMemoryError`. Version 4.2.15.Final contains a patch.

Severity

CVE-2026-44893 (GCVE-0-2026-44893)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:00 – Updated: 2026-08-05 12:14

Title

Netty: HAProxy SSL TLV parsing leaks retained slice on invalid TLV length

Summary

Netty is a network application framework for development of protocol servers and clients. In netty-codec-haproxy prior to versions 4.1.135.Final and 4.2.15.Final, when decoding a PP2_TYPE_SSL TLV, HAProxyMessage.readNextTLV() first calls `header.retainedSlice(header.readerIndex(), length)` and only then reads the 1-byte client field and 4-byte verify field. If the attacker sets the TLV length below 5, the subsequent readByte/readInt throws IndexOutOfBoundsException. HAProxyMessageDecoder only catches HAProxyProtocolException around this call, so the IOOBE propagates and the retained slice on the pooled cumulation buffer is never released. Versions 4.1.135.Final and 4.2.15.Final patch the issue.

CVE-2026-44894 (GCVE-0-2026-44894)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:06 – Updated: 2026-07-15 00:53

Title

Netty's Default QUIC token handler accepts any client-supplied token

Summary

Netty is a network application framework for development of protocol servers and clients. NoQuicTokenHandler is the tokenHandler used when the application does not set one. Prior to version 4.2.15.Final, its writeToken() returns false (server will not send Retry — acceptable), but validateToken() unconditionally `return 0`. In QuicheQuicServerCodec.handlePacket(), a non-negative return from validateToken() is interpreted as 'token is valid, ODCID starts at offset 0', causing the server to call quiche_accept as if the client's address had been validated by a Retry round-trip. Per RFC 9000 §8.1, a validated address lifts the 3× anti-amplification send limit. Thus any attacker who includes ANY non-empty token bytes in an Initial packet — with a spoofed victim source IP — causes the Netty server to treat the victim as validated and reflect full-size handshake flights (certificates, etc.) toward it without the 3× cap. The correct 'no token handler' semantics would be to return -1 (invalid) so the normal un-validated path and amplification limit apply. Version 4.2.15.Final patches the issue.

Per RFC 9000 \u00a78.1, a validated address lifts the 3\u00d7 anti-amplification send limit. Thus any attacker who includes ANY non-empty token bytes in an Initial packet \u2014 with a spoofed victim source IP \u2014 causes the Netty server to treat the victim as validated and reflect full-size handshake flights (certificates, etc.) toward it without the 3\u00d7 cap. The correct \u0027no token handler\u0027 semantics would be to return -1 (invalid) so the normal un-validated path and amplification limit apply. Version 4.2.15.Final patches the issue."

CVE-2026-45416 (GCVE-0-2026-45416)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:10 – Updated: 2026-08-10 12:05

Title

Netty: SNI handler pre-allocates up to 16 MiB from nine attacker bytes

Summary

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, SslClientHelloHandler.decode() reads the 24-bit TLS handshake length and, when the ClientHello does not fit in the first record, eagerly allocates `ctx.alloc().buffer(handshakeLength)` (line 161). The guard at line 140 is `handshakeLength > maxClientHelloLength && maxClientHelloLength != 0`, and the commonly-used SniHandler/AbstractSniHandler constructors (SniHandler(Mapping), SniHandler(AsyncMapping), AbstractSniHandler()) pass maxClientHelloLength=0 and handshakeTimeoutMillis=0, so the length guard is disabled and no timeout is scheduled. A 16 MiB request exceeds the default pooled chunk size and becomes a huge/unpooled allocation performed immediately. The buffer is retained in the handler until the channel closes. Versions 4.1.135.Final and 4.2.15.Final patch the issue.

The guard at line 140 is `handshakeLength \u003e maxClientHelloLength \u0026\u0026 maxClientHelloLength != 0`, and the commonly-used SniHandler/AbstractSniHandler constructors (SniHandler(Mapping), SniHandler(AsyncMapping), AbstractSniHandler()) pass maxClientHelloLength=0 and handshakeTimeoutMillis=0, so the length guard is disabled and no timeout is scheduled. A 16 MiB request exceeds the default pooled chunk size and becomes a huge/unpooled allocation performed immediately. The buffer is retained in the handler until the channel closes.

CVE-2026-45536 (GCVE-0-2026-45536)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:12 – Updated: 2026-06-12 15:05

Title

Netty: Unix-socket fd receive leaks descriptors when peer sends two at once

Summary

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, netty_unix_socket_recvFd sets msg_control to `char control[CMSG_SPACE(sizeof(int))]` (line 940) — 24 bytes on 64-bit Linux. A peer-sent SCM_RIGHTS cmsg carrying two ints has cmsg_len = CMSG_LEN(8) = 24, which fits exactly with no MSG_CTRUNC, so the kernel installs both fds in the receiving process. The subsequent check `cmsg->cmsg_len == CMSG_LEN(sizeof(int))` (line 972, expected 20) fails, the branch that would read the fd is skipped, and neither installed fd is closed. The for(;;) loop calls recvmsg again (non-blocking → EAGAIN → Java maps to 0 → read loop exits normally), leaving two leaked fds per message. There is no MSG_CTRUNC handling. Reachable via Epoll/KQueue DomainSocketChannel when the application opts into DomainSocketReadMode.FILE_DESCRIPTORS (non-default). Versions 4.1.135.Final and 4.2.15.Final patch the issue.

CVE-2026-45673 (GCVE-0-2026-45673)

Vulnerability from cvelistv5 – Published: 2026-06-12 14:16 – Updated: 2026-06-12 16:05

Title

Netty: DNS Cache Poisoning due to Predictable PRNG and Default Static Source Port

Summary

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, Netty's DNS resolver uses a predictable PRNG for generating DNS transaction IDs and defaults to a static UDP source port. This combination reduces the entropy of DNS queries, enabling DNS Cache Poisoning (Kaminsky attack). Versions 4.1.135.Final and 4.2.15.Final patch the issue.

Severity

6.8 (Medium)
