Compiler Optimization Removal or Modification of Security-critical Code
Overview Affected versions of this package are vulnerable to Compiler Optimization Removal or Modification of Security-critical Code due to a race condition in AESNI detection when certain compiler optimizations are applied. An attacker can extract sensitive cryptographic keys or perform...
LoRAShield: Data-Free Editing Alignment for Secure Personalized LoRA Sharing
The proliferation of Low-Rank Adaptation LoRA models has democratized personalized text-to-image generation, enabling users to share lightweight models e.g., personal portraits on platforms like Civitai and Liblib. However, this "share-and-play" ecosystem introduces critical risks: benign LoRAs c...
SPA: Towards More Stealth and Persistent Backdoor Attacks in Federated Learning
Federated Learning FL has emerged as a leading paradigm for privacy-preserving distributed machine learning, yet the distributed nature of FL introduces unique security challenges, notably the threat of backdoor attacks. Existing backdoor strategies predominantly rely on end-to-end label...
[SECURITY] Fedora 42 Update: optipng-7.9.1-1.fc42
OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats BMP, GIF, PNM and TIFF to optimized PNG, and performs PNG integrity checks and corrections...
How AI-Enabled Workflow Automation Can Help SOCs Reduce Burnout
It sure is a hard time to be a SOC analyst. Every day, they are expected to solve high-consequence problems with half the data and twice the pressure. Analysts are overwhelmed—not just by threats, but by the systems and processes in place that are meant to help them respond. Tooling is fragmented...
Security Assessment of DeepSeek and GPT Series Models against Jailbreak Attacks
The widespread deployment of large language models LLMs has raised critical concerns over their vulnerability to jailbreak attacks, i.e., adversarial prompts that bypass alignment mechanisms and elicit harmful or policy-violating outputs. While proprietary models like GPT-4 have undergone extensi...
IDOL: Improved Different Optimization Levels Testing for Solidity Compilers
As blockchain technology continues to evolve and mature, smart contracts have become a key driving force behind the digitization and automation of transactions. Smart contracts greatly simplify and refine the traditional business transaction processes, and thus have had a profound impact on vario...
Smart-LLaMA-DPO: Reinforced Large Language Model for Explainable Smart Contract Vulnerability Detection
Smart contract vulnerability detection remains a major challenge in blockchain security. Existing vulnerability detection methods face two main issues: 1 Existing datasets lack comprehensive coverage and high-quality explanations for preference learning. 2 Large language models LLMs often struggl...
Cut Tracing with E-Graphs for Boolean FHE Circuit Synthesis
Fully Homomorphic Encryption FHE is a promising privacy-preserving technology enabling secure computation over encrypted data. A major limitation of current FHE schemes is their high runtime overhead. As a result, automatic optimization of circuits describing FHE computation has garnered...
Optimizing System Latency for Blockchain-Encrypted Edge Computing in Internet of Vehicles
As Internet of Vehicles IoV technology continues to advance, edge computing has become an important tool for assisting vehicles in handling complex tasks. However, the process of offloading tasks to edge servers may expose vehicles to malicious external attacks, resulting in information loss or...
On Secure UAV-Aided ISCC Systems
Integrated communication and sensing, which can make full use of the limited spectrum resources to perform communication and sensing tasks simultaneously, is an up-and-coming technology in wireless communication networks. In this work, we investigate the secrecy performance of an uncrewed aerial...
Secure Time-Modulated Intelligent Reflecting Surface via Generative Flow Networks
We propose a novel directional modulation DM design for OFDM transmitters aided by a time-modulated intelligent reflecting surface TM-IRS. The TM-IRS is configured to preserve the integrity of transmitted signals toward multiple legitimate users while scrambling the signal in all other directions...

CVE-2022-50118
CVE-2022-50118 describes a Linux kernel issue in the PowerPC perf PMU path. A new pmi_irq_pending check in hw_irq.h is used by power_pmu_disable to warn if PMI is pending when no counter overflows. The patch set removes the WARN_ON for PMI in this scenario and adds an optimization to clear pendin...
CVE-2022-50100
CVE-2022-50100 affects the Linux kernel sched/core: Do not requeue a task on a CPU excluded from cpus_mask.
