Scalable APT Malware Classification Via Parallel Feature Extraction and GPU-Accelerated Learning

This paper presents an underlying framework for both automating and accelerating malware classification, more specifically, mapping malicious executables to known Advanced Persistent Threat APT groups. The main feature of this analysis is the assembly-level instructions present in executables whi...

xorg: xwayland: Use of uninitialized pointer in compRedirectWindow()

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow will return a BadAlloc error without validating the window tree marked just before, which leaves the...

Attack-Defense Trees with Offensive and Defensive Attributes (With Appendix)

Effective risk management in cybersecurity requires a thorough understanding of the interplay between attacker capabilities and defense strategies. Attack-Defense Trees ADTs are a commonly used methodology for representing this interplay; however, previous work in this domain has only focused on...

OpCode-Based Malware Classification Using Machine Learning and Deep Learning Techniques

This technical report presents a comprehensive analysis of malware classification using OpCode sequences. Two distinct approaches are evaluated: traditional machine learning using n-gram analysis with Support Vector Machine SVM, K-Nearest Neighbors KNN, and Decision Tree classifiers; and a deep...

UBUNTU-CVE-2025-22079

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate ltreedepth to avoid out-of-bounds access The ltreedepth field is 16-bit le16, but the actual maximum depth is limited to OCFS2MAXPATHDEPTH. Add a check to prevent out-of-bounds access if ltreedepth has an invalid...
