CVE-2026-52973

A flaw was found in the Linux kernel's futex subsystem. The needfutexhashallocatedefault function incorrectly relies on CLONETHREAD semantics, which can lead to non-concurrency issues when memory allocations mm-futexref pcpu allocations are shared across CLONEVM clones, excluding vfork. This can...

CVE-2026-41000

The CVE-2026-41000 issue affects Spring Web Services where Wss4jSecurityInterceptor did not consistently wire Apache WSS4J ReplayCache instances into RequestData for validation-time checks. This undermines protections against replay of UsernameToken nonces and creation timestamps, as well as Time...

PT-2026-47315

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of a mapping state maintained for a sparse memory allocation. The product accidentally refers to the wrong memory due to the semantics of how math operations are implicitly scaled acro...

RedEdit: Agentic Red-Teaming of Image Safety Classifiers Via MCTS-Guided Photo-Editing

Image safety classifiers serve as a critical component of contemporary content moderation systems on the internet. However, their resilience against user-style malicious image editing remains underexplored. Such behaviors are highly prevalent in daily scenarios but difficult to fully reproduce. T...

Astra Linux - уязвимость в firefox

The ShmemCharMapHashEntry code was susceptible to potentially undefined behavior by bypassing the move semantics for one of its data members. This vulnerability affects Firefox versions less than 126...

Awakening the Hydra: Stabilizing Multi-Concept Backdoor Injection in Text-To-Image Diffusion Models

Text-to-image diffusion models are increasingly developed through open-source reuse and repeated downstream fine-tuning, where reused checkpoints are difficult to verify and thus more susceptible to hidden backdoor behaviors. In such ecosystems, a single pretrained model may be sequentially adapt...

One Step Further: Understanding PLC Binaries through Cross-Platform Reverse Engineering and Function-Level Semantic Analysis

As emerging attacks increasingly target Industrial Control Systems ICS, the security of Programmable Logic Controllers PLCs has become a critical concern. Binary Code Analysis BCA, which enables analysts to understand compiled programs without source code, is essential for ICS security tasks such...

Double-free in `vmem` storage reachable from safe Rust

When the vmem feature is enabled, VmemStorage::newBox and every public constructor that funnels through it — ConcurrentHeapRB::defaultcap, ConcurrentHeapRB::fromVec, From, etc. bit-copies the input buffer into a freshly mmap'd region with ptr::copynonoverlapping, then lets the source Box drop...

Veritas: A Semantically Grounded Agentic Framework for Memory Corruption Vulnerability Detection in Binaries

Detecting memory corruption vulnerabilities in stripped binaries requires recovering object semantics, interprocedural propagation, and feasible triggers from low-level, lossy representations. Recent LLM-based approaches improve code understanding, but reliable detection still requires grounding ...

Smart Contract Security beyond Detection

Smart contract security has progressed from vulnerability detection toward a broader research agenda that includes semantic reasoning, automated repair, adversarial robustness, and real-time exploit detection. This paper develops a capstone-oriented research narrative around four directions:...
