In the Linux kernel, the following vulnerability has been resolved: KVM: x86 – Mark the target gfn of the emulated atomic instruction as dirty When emulating an atomic access on behalf of the guest, mark the target gfn as dirty if the CMPXCHG instruction attempts to be executed and fails without ...
Astra Linux – Vulnerability in Qemu
An integer underflow issue was discovered in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could exploit this flaw to render QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service...
Astra Linux – Vulnerability in Qemu
A reachable assertion issue was detected in the USB EHCI emulation code of QEMU. This issue can occur during the processing of USB requests due to improper handling of the DMA memory map. A malicious privileged user within the guest environment may exploit this flaw to send invalid USB requests,...
Astra Linux – Vulnerability in Qemu
An infinite loop flaw was discovered in the USB xHCI controller emulation of QEMU while calculating the length of the Transfer Request Block TRB Ring. This flaw allows a privileged guest user to halt the QEMU process on the host, resulting in a denial of service...

Autonomous Adversary: Red-Teaming in the Age of LLM
Language Model Agents LMAs are emerging as a powerful primitive for augmenting red-team operations. They can support attack planning, adversary emulation, and the orchestration of multi-step activity such as lateral movement, a core enabling capability of advanced persistent threat APT campaigns...
A UEFI System with SPDM to Protect against Unauthorized Device Connections
Attackers willing to compromise computing systems can use malicious peripherals as an attack vector, threatening users that cannot verify the hardware's authenticity. To address this problem, our work uses the Security Protocol and Data Model to propose a UEFI system capable of authenticating PCI...
