{"id":"UBUNTU-CVE-2024-6505","details":"A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host.","modified":"2026-02-04T02:40:52.859856Z","published":"2024-07-05T14:15:00Z","related":["USN-7744-1"],"upstream":["CVE-2024-6505"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-6505"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-6505"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2024-6505"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7744-1"}],"affected":[{"package":{"name":"qemu","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/qemu@1:6.2+dfsg-2ubuntu6.27?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:6.2+dfsg-2ubuntu6.27"}]}],"versions":["1:6.0+dfsg-2expubuntu1","1:6.0+dfsg-2expubuntu2","1:6.0+dfsg-2expubuntu4","1:6.2+dfsg-2ubuntu5","1:6.2+dfsg-2ubuntu6","1:6.2+dfsg-2ubuntu6.1","1:6.2+dfsg-2ubuntu6.2","1:6.2+dfsg-2ubuntu6.3","1:6.2+dfsg-2ubuntu6.4","1:6.2+dfsg-2ubuntu6.5","1:6.2+dfsg-2ubuntu6.6","1:6.2+dfsg-2ubuntu6.7","1:6.2+dfsg-2ubuntu6.8","1:6.2+dfsg-2ubuntu6.9","1:6.2+dfsg-2ubuntu6.10","1:6.2+dfsg-2ubuntu6.11","1:6.2+dfsg-2ubuntu6.12","1:6.2+dfsg-2ubuntu6.13","1:6.2+dfsg-2ubuntu6.14","1:6.2+dfsg-2ubuntu6.15","1:6.2+dfsg-2ubuntu6.16","1:6.2+dfsg-2ubuntu6.17","1:6.2+dfsg-2ubuntu6.18","1:6.2+dfsg-2ubuntu6.19","1:6.2+dfsg-2ubuntu6.21","1:6.2+dfsg-2ubuntu6.22","1:6.2+dfsg-2ubuntu6.23","1:6.2+dfsg-2ubuntu6.24","1:6.2+dfsg-2ubuntu6.25","1:6.2+dfsg-2ubuntu6.26"],"ecosystem_specific":{"binaries":[{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-block-extra"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-guest-agent"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-arm"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-common"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-data"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-gui"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-mips"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-misc"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-ppc"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-s390x"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-sparc"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-x86"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-x86-microvm"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-system-x86-xen"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-user"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-user-binfmt"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-user-static"},{"binary_version":"1:6.2+dfsg-2ubuntu6.27","binary_name":"qemu-utils"}],"availability":"No
