The flaw exists within the handling of vmw_buffer_object objects. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. This flaw allows a local privileged user to escalate privileges and execute code in the context of the kernel." } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 6.7, "baseSeverity": "MEDIUM" }, "exploitabilityScore": 0.8, "impactScore": 5.9 }, { "source": "secalert@redhat.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 6.7, "baseSeverity": "MEDIUM" }, "exploitabilityScore": 0.8, "impactScore": 5.9 } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-415" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionEndIncluding": "6.3.9", "matchCriteriaId": "91F73DF0-B48A-4A70-A0C6-8844D289441D" } ] } ] }, { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*", "matchCriteriaId": "F4CFF558-3C47-480D-A2F0-BABF26042943" }, { "vulnerable": true, "criteria": "cpe:2.3:o:redhat:enterprise_linux:9.0:*:*:*:*:*:*:*", "matchCriteriaId": "7F6FB57C-2BC7-487C-96DD-132683AEB35D" } ] } ] } ], "references": [ { "url": "https://access.redhat.com/security/cve/CVE-2023-33952", "source": "secalert@redhat.com", "tags": [ "Third Party Advisory" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2218212", "source": "secalert@redhat.com", "tags": [ "Issue Tracking", "Patch", "Third Party Advisory" ] }, { "url": "https://www.zerodayinitiative.com/advisories/ZDI-CAN-20292", "source": "secalert@redhat.com", "tags": [ "Patch", "Third Party Advisory", "VDB Entry" ] } ] }
