Simultaneously Exposing and Jamming Covert Communications Via Disco Reconfigurable Intelligent Surfaces

Covert communications provide a stronger privacy protection than cryptography and physical-layer security PLS. However, previous works on covert communications have implicitly assumed the validity of channel reciprocity, i.e., wireless channels remain constant or approximately constant during the...

CVE-2025-47791

The vulnerability CVE-2025-47791 affects Nextcloud Server (self-hosted) and Nextcloud Enterprise Server prior to 28.0.13, 29.0.10, and 30.0.3. The issue is an improperly protected, currently unused endpoint used to verify a share recipient, which could proxy requests to another server. Affected v...

SafeTrans: LLM-Assisted Transpilation from C to Rust

Rust is a strong contender for a memory-safe alternative to C as a "systems" programming language, but porting the vast amount of existing C code to Rust is a daunting task. In this paper, we evaluate the potential of large language models LLMs to automate the transpilation of C code to idiomatic...

kernel: wifi: mac80211: don't use rate mask for offchannel TX either

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't use rate mask for offchannel TX either Like the commit ab9177d83c04 "wifi: mac80211: don't use rate mask for scanning", ignore incorrect settings to avoid no supported rate warning reported by syzbot. The...

kernel: icmp: change the order of rate limits

A flaw was found in the Linux kernel related to the order of rate limits for ICMP messages. The sequence in which rate limiters are applied potentially allows a side-channel attack, resulting in information disclosure...

Optimized Couplings for Watermarking Large Language Models

Large-language models LLMs are now able to produce text that is, in many cases, seemingly indistinguishable from human-generated content. This has fueled the development of watermarks that imprint a signal'' in LLM-generated text with minimal perturbation of an LLM's output. This paper provides a...

Sandcastles in the Storm: Revisiting the (Im)Possibility of Strong Watermarking

Watermarking AI-generated text is critical for combating misuse. Yet recent theoretical work argues that any watermark can be erased via random walk attacks that perturb text while preserving quality. However, such attacks rely on two key assumptions: 1 rapid mixing watermarks dissolve quickly...
