{"id":"USN-8161-1","summary":"qemu vulnerabilities","details":"It was discovered that the LSI53C895A SCSI Host Bus Adapter implementation\nof QEMU incorrectly handled memory. An attacker inside the guest could\npossibly use this issue to cause QEMU to crash, resulting in a denial of\nservice, or possibly execute arbitrary code. (CVE-2024-6519)\n\nIt was discovered that QEMU could be made to read out of bounds when\nreading VMDK images. If a user or an automated system were tricked into\nopening a specially crafted VMDK image, an attacker could possibly use\nthis issue to leak sensitive informaton or cause QEMU to crash, resulting\nin a denial of service. (CVE-2026-2243)\n\nIt was discovered that the virtio-snd device implementation of QEMU could\nbe made to write out of bounds. An attacker inside the guest could\npossibly use this issue to cause QEMU to crash, resulting in a denial of\nservice, or possibly execute arbitrary code. This issue only affected\nUbuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3195)\n\nIt was discovered that the virtio-snd device implementation of QEMU\ncontained an arithmetic overflow.
