The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an out-of-bounds write in the host heap memory and a potential denial of service (DoS) for the QEMU process.(CVE-2026-48914)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"qemu","purl":"pkg:rpm/openEuler/qemu&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-114.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["qemu-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-block-curl-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-block-iscsi-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-block-rbd-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-block-ssh-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-debuginfo-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-debugsource-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-guest-agent-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-hw-usb-host-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-img-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-system-aarch64-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-system-arm-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-system-riscv-6.2.0-114.oe2203sp4.aarch64.rpm","qemu-system-x86_64-6.2.0-114.oe2203sp4.aarch64.rpm"],"noarch":["qemu-help-6.2.0-114.oe2203sp4.noarch.rpm"],"src":["qemu-6.2.0-114.oe2203sp4.src.rpm"],"x86_64":["qemu-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-block-curl-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-block-iscsi-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-block-rbd-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-block-ssh-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-debuginfo-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-debugsource-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-guest-agent-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-hw-usb-host-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-img-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-seabios-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-system-aarch64-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-system-arm-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-system-riscv-6.2.0-114.oe2203sp4.x86_64.rpm","qemu-system-x86_64-6.2.0-114.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2951"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48914"}],"database_specific":{"severity":"Medium"}}
