What to do

AI-suggested

Red Hat has published an advisory describing the issue but does not explicitly confirm the availability of a patch in the provided content. Users should monitor the Red Hat advisory for updates regarding fixes. Until a fix is available, consider limiting access to affected QEMU virtio devices and applying any vendor-recommended mitigations if provided. No generic or unrelated mitigations are recommended.

Description

CVE-2024-8612 is a vulnerability in QEMU's virtio-scsi, virtio-blk, and virtio-crypto devices where the size parameter used in virtqueue_push may exceed the actual data size sent to the guest. This can cause uninitialized data in the bounce buffer to be written back, leading to an information leak. The vulnerability has a low CVSS score of 3.8 and does not require user interaction for exploitation.
