{"id": "CVE-2007-3732", "bulletinFamily": "NVD", "title": "CVE-2007-3732", "description": "In Linux 2.6 before 2.6.23, the TRACE_IRQS_ON function in iret_exc calls a C function without ensuring that the segments are set properly. The kernel's %fs needs to be restored before the call in TRACE_IRQS_ON and before enabling interrupts, so that \"current\" references work. Without this, \"current\" used in the window between iret_exc and the middle of error_code where %fs is reset, would crash.", "published": "2019-11-07T22:15:00", "modified": "2019-11-12T15:18:00", "cvss": {"score": 1.9, "vector": "AV:L/AC:M/Au:N/C:N/I:N/A:P"}, "href": "https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-3732", "reporter": "cve@mitre.org", "references": ["https://security-tracker.debian.org/tracker/CVE-2007-3732", "https://access.redhat.com/security/cve/cve-2007-3732", "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2007-3732"], "cvelist": ["CVE-2007-3732"], "type": "cve", "lastseen": "2021-02-02T05:31:25", "edition": 7, "viewCount": 1, "enchantments": {"dependencies": {"references": [], "modified": "2021-02-02T05:31:25", "rev": 2}, "score": {"value": 1.5, "vector": "NONE", "modified": "2021-02-02T05:31:25", "rev": 2}, "vulnersScore": 1.5}, "cpe": [], "affectedSoftware": [{"cpeName": "linux:linux_kernel", "name": "linux linux kernel", "operator": "lt", "version": "2.6.23"}], "cvss2": {"acInsufInfo": false, "cvssV2": {"accessComplexity": "MEDIUM", "accessVector": "LOCAL", "authentication": "NONE", "availabilityImpact": "PARTIAL", "baseScore": 1.9, "confidentialityImpact": "NONE", "integrityImpact": "NONE", "vectorString": "AV:L/AC:M/Au:N/C:N/I:N/A:P", "version": "2.0"}, "exploitabilityScore": 3.4, "impactScore": 2.9, "obtainAllPrivilege": false, "obtainOtherPrivilege": false, "obtainUserPrivilege": false, "severity": "LOW", "userInteractionRequired": false}, "cvss3": {"cvssV3": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 3.6}, "cpe23": [], "cwe": ["NVD-CWE-Other"], "scheme": null, "cpeConfiguration": {"CVE_data_version": "4.0", "nodes": [{"cpe_match": [{"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:2.6.23:*:*:*:*:*:*:*", "versionEndExcluding": "2.6.23", "versionStartIncluding": "2.6.0", "vulnerable": true}], "operator": "OR"}]}, "extraReferences": [{"name": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2007-3732", "refsource": "MISC", "tags": ["Patch", "Third Party Advisory", "Issue Tracking"], "url": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2007-3732"}, {"name": "https://access.redhat.com/security/cve/cve-2007-3732", "refsource": "MISC", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/security/cve/cve-2007-3732"}, {"name": "https://security-tracker.debian.org/tracker/CVE-2007-3732", "refsource": "MISC", "tags": ["Third Party Advisory"], "url": "https://security-tracker.debian.org/tracker/CVE-2007-3732"}]}
