EUVD-2026-86641

In the Linux kernel, the following vulnerability has been resolved: virtioinput: reset device if inputregisterdevice fails Probe marks the device DRIVEROK with virtiodeviceready before calling inputregisterdevice. If registration fails, the error path cleared vi-ready and called delvqs while the...

CVE-2026-97987

The Linux kernel contains a vulnerability in virtio_input where a device could maintain DMA access to queues that were already torn down. This occurs because the probe process marks the device as DRIVER_OK before calling input_register_device(); if registration fails, the error path cleared the v...

kernel: virtio-vdpa: Fix cpumask memory leak in virtio_vdpa_find_vqs()

A memory leak was found in the virtio-vdpa driver. The cpumask allocated by createaffinitymasks is not freed before the function returns, causing a small memory leak each time virtqueues are set up...
