CVE-2026-5590

A race condition during TCP connection teardown can cause tcprecv to operate on a connection that has already been released. If tcpconnsearch returns NULL while processing a SYN packet, a NULL pointer derived from stale context data is passed to tcpbacklogisfull and dereferenced without validatio...

NetSecBed: A Container-Native Testbed for Reproducible Cybersecurity Experimentation

Cybersecurity research increasingly depends on reproducible evidence, such as traffic traces, logs, and labeled datasets, yet most public datasets remain static and offer limited support for controlled re-execution and traceability, especially in heterogeneous multi-protocol environments. This...

CVE-2026-5474

A vulnerability was found in NASA cFS up to 7.0.0. This affects the function CFEMSGGetSize of the file apps/tolab/fsw/src/tolabpassthruencode.c of the component CCSDS Packet Header Handler. Performing a manipulation results in heap-based buffer overflow. The attacker must have access to the local...

SUSE CVE-2026-23453

In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg-prueth: Fix memory leak in XDPDROP for non-zero-copy mode Page recycling was removed from the XDPDROP path in emacrunxdp to avoid conflicts with AFXDP zero-copy mode, which uses xskbufffree instead. However, this...

CocoaMQTT: Denial of Service via Reachable Assertion in `PUBLISH` Packet Parsing

A vulnerability exists in the packet parsing logic of CocoaMQTT that allows an attacker or a compromised/malicious MQTT broker to remotely crash the host iOS/macOS/tvOS application. The vulnerability is located in Source/FramePublish.swift during the extraction of the Topic string from the incomi...

EUVD-2020-31212

Hirschmann HiOS devices versions prior to 08.1.00 and 07.1.01 contain a denial of service vulnerability in the EtherNet/IP stack where improper handling of packet length fields allows remote attackers to crash or hang the device. Attackers can send specially crafted UDP EtherNet/IP packets with a...

CVE-2026-31401

A flaw was found in the Linux kernel's Human Interface Device HID BPF Berkeley Packet Filter component. This vulnerability occurs in the hidhwrequest function, where an uncontrolled return value from dispatchhidbpfrawrequests can lead to a buffer overflow. This could allow a local attacker to cau...

EUVD-2026-18784

In the Linux kernel, the following vulnerability has been resolved: HID: bpf: prevent buffer overflow in hidhwrequest right now the returned value is considered to be always valid. However, when playing with HID-BPF, the return value can be arbitrary big, because it's the return value of...
