A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices. The size for virtqueue_push as set in virtio_scsi_complete_req / virtio_blk_req_complete / virito_crypto_req_complete could be larger than the true size of the data which has been sent to guest. Once virtqueue_push() finally calls dma_memory_unmap to ummap the in_iov, it may call the address_space_write function to write back the data. Some uninitialized data may exist in the bounce.buffer, leading to an information leak.

According to the versions of the qemu packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    A flaw was found in QEMU. An assertion failure was present in the usb_ep_get() function in hw/net/core.c     when trying to get the USB endpoint from a USB device. This flaw may allow a malicious unprivileged guest     user to crash the QEMU process on the host and cause a denial of service condition.(CVE-2024-8354)
