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-2026-46315

A flaw was found in the Linux kernel's iouring subsystem, specifically within the IORINGOPWAITID operation. This vulnerability occurs because the waitid information structure is not properly initialized before being copied to userspace. A local user could exploit this to expose stale data from...

CVE-2026-46315

CVE-2026-46315 affects the Linux kernel’s io_uring waitid path. The issue arises because IORING_OP_WAITID stores results in io_waitid::info and may copy stale data to userspace if the wait completes without a child event. The fix is to clear the result storage during prep so the kernel’s path mir...
