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-2023-54132

The CVE-2023-54132 details a Linux kernel erofs vulnerability: parsing a non-compact HEAD index when clusterofs is invalid can trigger a page fault (kernel crash) in z_erofs_decompress_queue handling, as seen in crafted images. Affected component is the erofs subsystem of the Linux kernel; impact...

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 Linux kernel that stems from parsing a non-compact HEAD index without stopping when clusterofs is invalid, which could result in a page fault...
