Astra Linux – Vulnerability in Qemu

A NULL pointer dereference flaw was discovered in the am53c974 SCSI host bus adapter emulation in QEMU in versions prior to 6.0.0. This issue occurs when handling the “Information Transfer” command. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a...

Astra Linux – Vulnerability in Qemu

An “off-by-one” error was detected in the SCSI device emulation in QEMU. This error could occur during the processing of MODE SELECT commands in modesensepage, if the ‘page’ argument is set to MODEPAGEALLS 0x3f. A malicious guest could exploit this flaw to potentially cause QEMU to crash, resulti...

Astra Linux – Vulnerability in Qemu

QEMU 4.2.0 has a use-after-free issue in hw/net/e1000ecore.c, as a user of the guest OS can trigger an e1000e packet with the data’s address set to the e1000e’s MMIO address...

Astra Linux – Vulnerability in Qemu

A divide-by-zero issue was discovered in dwc2handlepacket in hw/usb/hcd-dwc2.c, within the hcd-dwc2 USB host controller emulation in QEMU. A malicious guest could exploit this flaw to crash the QEMU process on the host, resulting in a denial of service...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QXL display device emulation in QEMU. The double retrieval of the guest-controlled values cursor-header.width and cursor-header.height can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. A malicious privileged gues...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: arm64: The issue was fixed in the concurrently setting of insnemulation sysctls. The emulationprochandler function changes table-data for procdointvecminmax. However, it may cause an OOPs error if called concurrently with itself:...

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...

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...

The vulnerability of the QEMU hardware emulation software, which allows a hacker to trigger a service failure

The vulnerability of the QEMU hardware emulation software is related to the allocation of unlimited memory. Exploiting this vulnerability can allow a hacker to cause a system failure...

SUSE CVE-2026-43133

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Always use vmcb01 in VMLOAD/VMSAVE emulation Commit cc3ed80ae69f "KVM: nSVM: always use vmcb01 to for vmsave/vmload of guest state" made KVM always use vmcb01 for the fields controlled by VMSAVE/VMLOAD, but it missed...

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...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the VMLOAD/VMSAVE emulation in KVM nSVM does not always utilize vmcb01, potentially...

CVE-2026-31724

A flaw was found in the Linux kernel's USB gadget Ethernet Emulation Model EEM function. This issue occurs when a USB gadget function disconnects, causing the related network device to not be properly removed. As a result, invalid links remain in the system's file system, known as dangling symbol...
