DEBIAN-CVE-2022-50625
In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: avoid SBSA UART accessing DMACR register Chapter "B Generic UART" in "ARM Server Base System Architecture" 1 documentation describes a generic UART interface. Such generic UART does not support DMA. In current...

CVE-2023-53749
CVE-2023-53749 is discussed across multiple sources as a Linux kernel issue: the x86 memory-clearing path in clear_user_rep_good() had incorrect exception-table annotations, which could lead to a kernel oops instead of -EFAULT when a user-space access faults. Upstream fixes remove the problematic...
CVE-2022-50614
CVE-2022-50614 is a Linux kernel vulnerability described as a fix for a panic in pci_endpoint_test caused by zero-length mappings in dma_map_single(). The root cause involves dma mapping of zero length triggering a kernel BUG in swiotlb.c on arm64, leading to a panic. The provided description sta...
PT-2025-49455
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.0-rc1rpci-dev+ 237 Description The Linux kernel contained a flaw in the pci endpoint test module where the dma map single function did not properly handle zero-length mappings, leading to a potential kernel...
PT-2025-49479
In the Linux kernel, the following vulnerability has been resolved: x86: fix clear user rep good exception handling annotation This code no longer exists in mainline, because it was removed in commit d2c95f9d6802 "x86: don't use REP GOOD or ERMS for user memory clearing" upstream. However, rather...
Towards Small Language Models for Security Query Generation in SOC Workflows
Analysts in Security Operations Centers routinely query massive telemetry streams using Kusto Query Language KQL. Writing correct KQL requires specialized expertise, and this dependency creates a bottleneck as security teams scale. This paper investigates whether Small Language Models SLMs can...

AgenticCyber: A GenAI-Powered Multi-Agent System for Multimodal Threat Detection and Adaptive Response in Cybersecurity
The increasing complexity of cyber threats in distributed environments demands advanced frameworks for real-time detection and response across multimodal data streams. This paper introduces AgenticCyber, a generative AI powered multi-agent system that orchestrates specialized agents to monitor...
Linux kernel 安全漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from ALSA usb-audio not properly limiting the size of the PCM transfer buffer, which could result in a buffer...
CVE-2025-40245
In the Linux kernel, the following vulnerability has been resolved: nios2: ensure that memblock.currentlimit is set when setting pfn limits On nios2, with CONFIGFLATMEM set, the kernel relies on memblockgetcurrentlimit to determine the limits of memmap, in particular for maxlowpfn. Unfortunately,...
USN-7910-2: Linux kernel (Azure) vulnerabilities
Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...
