3.8 · LOW

A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices.

Published Sep 20, 2024CWE-200EPSS 0.20%

Overview

CVE-2024-8612 is a low-severity vulnerability. It was published on September 20, 2024 and has a CVSS 3.1 base score of 3.8 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.8, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
