Description

qemu vulnerabilities It was discovered that the LSI53C895A SCSI Host Bus Adapter implementation of QEMU incorrectly handled memory. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2024-6519) It was discovered that QEMU could be made to read out of bounds when reading VMDK images. If a user or an automated system were tricked into opening a specially crafted VMDK image, an attacker could possibly use this issue to leak sensitive informaton or cause QEMU to crash, resulting in a denial of service. (CVE-2026-2243) It was discovered that the virtio-snd device implementation of QEMU could be made to write out of bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3195) It was discovered that the virtio-snd device implementation of QEMU contained an arithmetic overflow. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3196) It was discovered that the Hyper-V Synthetic Debugging device implementation of QEMU could me made to write out of bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-3842)
