{"id":"CVE-2024-8612","url":"https://www.cyber-defence.io/tools/cve/CVE-2024-8612","generatedAt":"2026-10-28T13:13:07.556Z","title":"Some uninitialized data may exist in the bounce.buffer, leading to an information leak.","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.","published":"2024-09-20T18:15:05.000Z","lastModified":"2026-06-17T08:22:59.000Z","status":"Deferred","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":3.8,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N"},"cwe":["CWE-200"],"affected":[],"epss":{"score":0.00204,"percentile":0.10304,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.20%).
