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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Out-of-bounds Read", "cweId": "CWE-125" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Red Hat", "product": { "product_data": [ { "product_name": "Red Hat Enterprise Linux 6", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unknown" } } ] } }, { "product_name": "Red Hat Enterprise Linux 7", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unknown" } }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unknown" } } ] } }, { "product_name": "Red Hat Enterprise Linux 8", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 8 Advanced Virtualization", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 9", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://access.redhat.com/security/cve/CVE-2024-6505", "refsource": "MISC", "name": "https://access.redhat.com/security/cve/CVE-2024-6505" }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2295760", "refsource": "MISC", "name": "https://bugzilla.redhat.com/show_bug.cgi?id=2295760" } ] }, "work_around": [ { "lang": "en", "value": "A viable mitigation for this vulnerability is to disable RSS on the nic/virtio driver. \nThis can be performed either with the following qemu-kvm command \"-device virtio-net-pci,rss=off\", or, alternatively, by directly modifying the KVM XML file to disable RSS using a standard configuration tool (ex. libvirt)." } ], "impact": { "cvss": [ { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 6.8, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "HIGH", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H", "version": "3.1" } ] } }
