So, all readers and writers need some basic protection to\navoid load/store-tearing.\n\nThis patch changes proc_douintvec() to use READ_ONCE() and WRITE_ONCE()\ninternally to fix data-races on the sysctl side. For now, proc_douintvec()\nitself is tolerant to a data-race, but we still need to add annotations on\nthe other subsystem's side."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["kernel/sysctl.c"], "versions": [{"version": "e7d316a02f683864a12389f8808570e37fb90aa3", "lessThan": "d5d54714e329f646bd7af4994fc427d88ee68936", "status": "affected", "versionType": "git"}, {"version": "e7d316a02f683864a12389f8808570e37fb90aa3", "lessThan": "d335db59f7fb3353f56e52371f1ee796ae9c8f09", "status": "affected", "versionType": "git"}, {"version": "e7d316a02f683864a12389f8808570e37fb90aa3", "lessThan": "630c76850d554d7140232e71b5d1663e88cffb54", "status": "affected", "versionType": "git"}, {"version": "e7d316a02f683864a12389f8808570e37fb90aa3", "lessThan": "4762b532ec9539755aab61445d5da6e1926ccb99", "status": "affected", "versionType": "git"}, {"version": "70cd763eb1574cac07138be91f474a661e02d694", "status": "affected", "versionType": "git"}, {"version": "f4cea51e9a3d536e2ca2b74a958f7c0b4ea733c3", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["kernel/sysctl.c"], "versions": [{"version": "4.8", "status": "affected"}, {"version": "0", "lessThan": "4.8", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.132", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.56", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.18.13", "lessThanOrEqual": "5.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.19", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "5.10.132"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "5.15.56"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "5.18.13"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "5.19"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.4.24"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.7.7"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/d5d54714e329f646bd7af4994fc427d88ee68936"}, {"url": "https://git.kernel.org/stable/c/d335db59f7fb3353f56e52371f1ee796ae9c8f09"}, {"url": "https://git.kernel.org/stable/c/630c76850d554d7140232e71b5d1663e88cffb54"}, {"url": "https://git.kernel.org/stable/c/4762b532ec9539755aab61445d5da6e1926ccb99"}], "title": "sysctl: Fix data races in proc_douintvec().", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"metrics": [{"cvssV3_1": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 4.7, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "HIGH", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE"}}, {"other": {"type": "ssvc", "content": {"id": "CVE-2022-49641", "role": "CISA Coordinator", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "version": "2.0.3", "timestamp": "2025-10-01T19:33:58.576694Z"}}}], "problemTypes": [{"descriptions": [{"lang": "en", "type": "CWE", "cweId": "CWE-362", "description": "CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')"}]}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T19:36:48.974Z"}}]}}
