USN-8861-1 openssl vulnerabilities

It was discovered that OpenSSL had an inefficient algorithm in its QUIC stream reassembly implementation. A remote attacker could possibly use this issue to cause OpenSSL to use excessive CPU resources, leading to a denial of service. CVE-2026-42772 It was discovered that OpenSSL did not properly...

openssl: openssl: Denial of Service via inefficient QUIC stream reassembly

A flaw was found in OpenSSL. A remote attacker who establishes a QUIC network connection can cause a Denial of Service DoS by sending specially sequenced, out-of-order stream frames. Because the stream reassembly mechanism handles non-sequential data fragments inefficiently, processing these fram...

CVE-2026-42772

Issue summary: The QUIC stream reassembly algorithm performance deteriorates progressively as packets are arriving out of order. The worst case has a quadratic complexity proportional to the number of stream frames kept in the buffer for the received stream data. Impact summary: A remote QUIC pee...

CVE-2026-45765 Suricata dnp3: unbounded reassembly can lead to resource exhaustion

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, DNP3 reassembly could buffer data without sufficient parser-level bounds. Crafted DNP3 traffic may cause Suricata to consume excessive memory,...

GHSA-4W2J-M93H-CJ5J Quinn: Remote memory exhaustion in quinn-proto from unbounded out-of-order stream reassembly

Summary The Assembler component that assembles unordered stream fragments into consecutive chunks of the stream incurs some overhead for non-contiguous fragments. Readers that read from a RecvStream in order through an AsyncRead impl for example will be sensitive to peers that send fragments whil...

CVE-2026-25800

Quinn-quic: The Assembler handling unordered stream fragments can cause high memory overhead and potential memory exhaustion for non-contiguous fragments when reading RecvStream via AsyncRead, in versions 0.1.0 through 0.11.14. The issue arises from overhead in defragmentation of fragments with g...

GHSA-5XRH-QMMQ-W6CH Netty: SCTP reassembly nests buffers without bound

For each non-complete SctpMessage fragment the handler does fragments.putstreamId, Unpooled.wrappedBufferfrag, byteBuf, wrapping the previous accumulator and the new slice into a new CompositeByteBuf every time. After N fragments the accumulator is an N-deep chain of composites, each holding...

CVE-2026-22258

Suricata is a network IDS, IPS and NSM engine. Prior to versions 8.0.3 and 7.0.14, crafted DCERPC traffic can cause Suricata to expand a buffer w/o limits, leading to memory exhaustion and the process getting killed. While reported for DCERPC over UDP, it is believed that DCERPC over TCP and SMB...

CVE-2026-22258

CVE-2026-22258 affects Suricata (IDS/IPS/NSM). Before versions 8.0.3 and 7.0.14, crafted DCERPC traffic can trigger unbounded buffering, causing memory exhaustion and process termination. While initially observed over UDP, TCP and SMB are also considered vulnerable; however, DCERPC/TCP defaults l...
