Astra Linux - уязвимость в ffmpeg

A issue was discovered in the function filterframe in libavfilter/vflenscorrection.c in Ffmpeg 4.2.1. This issue allows attackers to cause a Denial of Service or other unspecified impacts due to a division by zero...

Astra Linux - уязвимость в libpng1.6

LIBPNG is a reference library used in applications that read, create, and manipulate PNG Portable Network Graphics raster image files. Prior to version 1.6.52, there was an out-of-bounds read vulnerability in libpng’s simplified API, allowing for reading of up to 10^12 bytes beyond the...

Fundamental Limitations of Post-Quantum Cryptographic Architectures

Modern lattice-based cryptography, particularly the learning with errors paradigm, relies on injecting artificial noise to secure data against quantum adversaries. This study systematically examines the theoretical and physical boundaries of this noise-reliant model across four interconnected...

In the Linux kernel, the following vulnerability has been resolved: spi: amlogic: spifc-a4: unregister ECC engine on probe failure and remove callback aml sfc probe registers the on-host NAND ECC engine, but teardown was missing from both probe unwind and remove-time cleanup. Add a devm cleanup...

PT-2026-35495

In the Linux kernel, the following vulnerability has been resolved: EDAC/mc: Fix error path ordering in edac mc alloc When the mci-pvt info allocation in edac mc alloc fails, the error path will call put device which will end up calling the device's release function. However, the init ordering is...

AgentVisor: Defending LLM Agents against Prompt Injection Via Semantic Virtualization

Large Language Model LLM agents are increasingly used to automate complex workflows, but integrating untrusted external data with privileged execution exposes them to severe security risks, particularly direct and indirect prompt injection. Existing defenses face significant challenges in balanci...

AI Chatbots and Trust

All the leading AI chatbots are sycophantic, and that's a problem: Participants rated sycophantic AI responses as more trustworthy than balanced ones. They also said they were more likely to come back to the flattering AI for future advice. And critically ­ they couldn't tell the difference betwe...
