CVE-2026-4769

Certain devices in the WAGO System I/O Field series activate an internal diagnostic capability during the initial startup sequence. This functionality is not formally documented and becomes accessible without authentication for a brief period in the early boot phase. During this window, an...

kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...

CVE-2026-53322

A flaw was found in the Linux kernel's vfio/pci subsystem. During device shutdown, an improper order of operations in cleaning up Direct Memory Access Buffers DMABUFs before disabling the function creates a brief window. In this window, a device's Base Address Registers BARs could still be access...

CVE-2026-53294

In the Linux kernel, the following vulnerability has been resolved: mailbox: mailbox-test: don't free the reused channel The RX channel can be aliased to the TX channel if it has a different MMIO. This special case needs to be handled when freeing the channels otherwise a double-free occurs...

PT-2026-51660

Name of the Vulnerable Software and Affected Versions GeoVision GV-I/O Box 4E version 2.09 Description OS command injection flaws exist in the libNetSetObj.so internal library, which is used to configure the network stack. A remote attacker can execute arbitrary commands by sending a specially...

CVE-2026-42487 x86 HVM I/O port list traversal

HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses therefore needs...

CVE-2026-0647

The 1794-AENTR adapter (Rockwell Automation FLEX I/O dual‑port EtherNet/IP) has an improper authentication flaw in its embedded web server. An unauthenticated attacker can change the device web interface password by sending a crafted HTTP GET request to a specific endpoint, without prior authenti...

CVE-2026-0646

The affected product is Rockwell Automation 1794-AENTR adapters (EtherNet/IP). The issue is a denial-of-service caused by improper memory handling of CIP protocol requests in the 1794-AENTR adapter, which can cause the device to fault and drop connections to its linked I/O modules, requiring a ma...

CVE-2026-45782

Cloud Hypervisor is a Virtual Machine Monitor for Cloud workloads. From version 21.0 to before version 51.2, a guest can cause a use-after-free in the cloud-hypervisor process by submitting two virtio-block descriptor chains that reuse the same headindex while asynchronous block I/O is enabled e....

CVE-2026-45782 Cloud Hypervisor: Use-after-free in virtio-block Async I/O Completion

Cloud Hypervisor is a Virtual Machine Monitor for Cloud workloads. From version 21.0 to before version 51.2, a guest can cause a use-after-free in the cloud-hypervisor process by submitting two virtio-block descriptor chains that reuse the same headindex while asynchronous block I/O is enabled e....

CVE-2026-45782

Cloud Hypervisor (virtio-block) is affected from 21.0 up to before 51.2. The issue arises in asynchronous virtio-block I/O completion when two descriptor chains reuse the same head_index, allowing a use-after-free that corrupts a bounce buffer if the duplicate operation completes before the origi...

CVE-2026-49955 Hermes WebUI < 0.51.270 Resource Exhaustion via passkey/options

Hermes WebUI before version 0.51.270 contains a resource exhaustion vulnerability that allows unauthenticated remote attackers to degrade service availability by repeatedly calling the passkey options endpoint without completing assertion. Attackers can send unlimited POST requests to the...

CVE-2024-36332

Improper isolation of GPU HW register space could allow a privileged attacker in malicious Guest Virtual Machine VM to perform unauthorized access to specific victim range of GPU MMIO register space, potentially causing the host OS to reboot and creating a Denial of Service DOS condition...

CVE-2026-45944

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit VT-d Virtualization Technology for Directed I/O component. When a context entry is being torn down, the 'Present' bit might not be cleared before other parts of the entry are zeroed. This can lead to the hardware...
