The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nvme-tcp: fix host memory disclosure on R2T for a read command nvmetcphandler2t does not check the direction of the request the R2T refers to. A malicious...

modbus-scanner

Modbus 检测扫描器 一个使用 libmodbus 的多线程 C 语言扫描器，用于检测 Modbus/TCP 服务。 该扫描器不仅仅依赖 TCP 端口 502 是否开放。相反，它会建立 Modbus/TCP 连接并发送应用层 Modbus 请求。有效的 Modbus 响应被用作判断 Modbus 服务存在的主要指标。 Modbus/TCP Modbus 是一种工业通信协议，通常被 PLC、RTU、HMI、SCADA 系统、传感器、仪表以及其他工业设备所使用。 Modbus/TCP 通过 TCP 传输 Modbus 应用协议。 标准的 Modbus/TCP 端口是：...

CVE-2026-89481

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express over TCP nvme-tcp component. A malicious NVMe controller can exploit this vulnerability by sending a Ready to Transfer R2T command for a read request. The host system, failing to properly validate the request direction, will...

CVE-2026-89482

A flaw was found in the nvme-tcp module of the Linux kernel. This vulnerability arises from improper handling of C2HData for REQOPWRITEZEROES commands, where the system fails to adequately validate the data length. A remote attacker could exploit this by sending specially crafted C2HData, leading...

CVE-2026-89480

A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...

CVE-2026-80788

A flaw was found in the Linux kernel's nvmet-tcp component. A remote attacker can send a specially crafted command with an oversized Scatter-Gather List SGL allocation. This can lead to an excessive memory allocation, triggering a kernel warning. On systems configured to panic on warnings, this...

CVE-2026-89482

CVE-2026-89482 is a wild-memory-access vulnerability in the Linux kernel's nvme-tcp module. The root cause is an incorrect receive-side gate: for REQ_OP_WRITE_ZEROES commands, blk_rq_payload_bytes() returns a non-zero value despite the absence of physical segments, so the setup phase leaves req-&...
