Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the rtw8822bsetantenna function being called during chip power-off conditions. This may trigger a...
Beamforming Feedback As a Novel Attack Surface for Wi-Fi Physical-Layer Security
With the rapid evolution of wireless technologies, Wi-Fi has expanded beyond its original role in data transmission to support various emerging applications, particularly in physical-layer security, including device authentication, user authentication, and secret key generation. Despite extensive...
Artificial Noise Versus Artificial Noise Elimination: Redefining Scaling Laws of Physical Layer Security
Artificial noise AN is a key physical-layer security scheme for wireless communications over multiple-input multiple-output wiretap channels. Recently, artificial noise elimination ANE has emerged as a strategy to mitigate the impact of AN on eavesdroppers. However, the influence of ANE on the...
SpyDir: Spy Device Localization through Accurate Direction Finding
Hidden spy cameras have become a great privacy threat recently, as these low-cost, low-power, and small form-factor IoT devices can quietly monitor human activities in the indoor environment without generating any side-channel information. As such, it is difficult to detect and even more...
Azure Linux 3.0 Security Update: kernel (CVE-2024-47714)
The version of kernel installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-47714 advisory. - In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: use hweight16 to get...
Secure Wireless Communication Using Distributed Coherent Transmission and Spatial Signal Decomposition
We present a new approach to secure wireless communications using coherent distributed transmission of signals that are spatially decomposed between a two-element distributed antenna array. High-accuracy distributed coordination of microwave wireless systems supports the ability to transmit...
PT-2026-38922
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the rtw88 wireless driver where the rtw8822b set antenna function can be called from userspace while the chip is powered off. This sequence triggers a warning in the...
Trustworthy GenAI over 6G: Integrated Applications and Security Frameworks
The integration of generative artificial intelligence GenAI into 6G networks promises substantial performance gains while simultaneously exposing novel security vulnerabilities rooted in multimodal data processing and autonomous reasoning. This article presents a unified perspective on cross-doma...
D-Link DIR600L 安全漏洞
D-Link DIR600L is a wireless router for home users, belonging to D-Link's "Cloud Router" series, with an external antenna design, supporting 802.11n standard, with a maximum wireless transmission rate of 150Mbps. The D-Link DIR600L suffers from a buffer overflow vulnerability, which originates fr...
C/N0 Analysis-Based GPS Spoofing Detection with Variable Antenna Orientations
GPS spoofing poses a growing threat to aviation by falsifying satellite signals and misleading aircraft navigation systems. This paper demonstrates a proof-of-concept spoofing detection strategy based on analyzing satellite Carrier-to-Noise Density Ratio C/N$0$ variation during controlled static...
