However\nthis is not the case for the idle threads of the secondary boot harts.\nTheir stacks overlap with their pt_regs, so both may get corrupted.\n\nSimilar issue has been fixed for the primary hart, see c7cdd96eca28\n(\"riscv: prevent stack corruption by reserving task_pt_regs(p) early\").\nHowever that fix was not propagated to the secondary harts. The problem\nhas been noticed in some CPU hotplug tests with V enabled. The function\nsmp_callin stored several registers on stack, corrupting top of pt_regs\nstructure including status field. As a result, kernel attempted to save\nor restore inexistent V context."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-787"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2024-38667", "ASSIGNER": "cve@kernel.org"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.8, "attackVector": "LOCAL", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH"}, "impactScore": 5.9, "exploitabilityScore": 1.8}}, "publishedDate": "2024-06-24T14:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:6.10:rc1:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.6.33", "versionStartIncluding": "6.2"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.9.4", "versionStartIncluding": "6.7"}, {"cpe23Uri": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "6.1.93", "versionStartIncluding": "5.7"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2025-05-30T19:30Z"}
