Heap grooming around the freed slab object yields an arbitrary-read primitive.\nI:H - lpfc_rq_buf_free() performs a list_del() write into the freed object and re-posts stale DMA addresses to the hardware RQ, causing the HBA to DMA attacker-supplied FC frame content into freed/reallocated kernel memory \u2014 a remote, attacker-controlled kernel write primitive, plus double-free-based heap control.\nA:H - The double kfree()/dma_pool_free() and freed-list corruption reliably produce slab corruption, BUG_ON in the allocator, or an oops in the interrupt-context completion handler, panicking the storage target host."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "ab34084f42ee06a9028d67c78feafb911d33d111", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "baa39f6ad79d372a6ce0aa639fbb2f1578479f57", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "95b63d15fce5c54a73bbf195e1aacb5a75b128e2", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "55658c7501467ca9ef3bd4453dd920010db8bc13", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "d96cc9a1b57725930c60b607423759d563b4d900", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "367cb5ffd8a8a4c85dc89f55e7fa7cc191425b11", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "897f64b01c1249ac730329b83f4f40bab71e86c7", "versionType": "git"}, {"status": "affected", "version": "472e146d1cf3410a898b49834500fa9e33ac41a2", "lessThan": "9dba9a45c348e8460da97c450cddf70b2056deb3", "versionType": "git"}], "programFiles": ["drivers/scsi/lpfc/lpfc_nvmet.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "5.1"}, {"status": "unaffected", "version": "0", "lessThan": "5.1", "versionType": "semver"}, {"status": "unaffected", "version": "5.4.299", "versionType": "semver", "lessThanOrEqual": "5.4.*"}, {"status": "unaffected", "version": "5.10.243", "versionType": "semver", "lessThanOrEqual": "5.10.*"}, {"status": "unaffected", "version": "5.15.192", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.151", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.105", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.12.46", "versionType": "semver", "lessThanOrEqual": "6.12.*"}, {"status": "unaffected", "version": "6.16.6", "versionType": "semver", "lessThanOrEqual": "6.16.*"}, {"status": "unaffected", "version": "6.17", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["drivers/scsi/lpfc/lpfc_nvmet.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/ab34084f42ee06a9028d67c78feafb911d33d111"}, {"url": "https://git.kernel.org/stable/c/baa39f6ad79d372a6ce0aa639fbb2f1578479f57"}, {"url": "https://git.kernel.org/stable/c/95b63d15fce5c54a73bbf195e1aacb5a75b128e2"}, {"url": "https://git.kernel.org/stable/c/55658c7501467ca9ef3bd4453dd920010db8bc13"}, {"url": "https://git.kernel.org/stable/c/d96cc9a1b57725930c60b607423759d563b4d900"}, {"url": "https://git.kernel.org/stable/c/367cb5ffd8a8a4c85dc89f55e7fa7cc191425b11"}, {"url": "https://git.kernel.org/stable/c/897f64b01c1249ac730329b83f4f40bab71e86c7"}, {"url": "https://git.kernel.org/stable/c/9dba9a45c348e8460da97c450cddf70b2056deb3"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: lpfc: Fix buffer free/clear order in deferred receive path\n\nFix a use-after-free window by correcting the buffer release sequence in\nthe deferred receive path.

El c\u00f3digo liberaba primero el b\u00fafer RQ y solo entonces borraba el puntero de contexto bajo el bloqueo. Rutas concurrentes (p. ej., ABTS y la ruta de republicaci\u00f3n) tambi\u00e9n inspeccionan y liberan el mismo puntero bajo el bloqueo, por lo que el orden antiguo podr\u00eda llevar a una doble liberaci\u00f3n/UAF.\n\nTenga en cuenta que la ruta de republicaci\u00f3n ya utiliza el patr\u00f3n correcto: desvincular el puntero bajo el bloqueo, luego liberarlo despu\u00e9s de soltar el bloqueo. La ruta diferida deber\u00eda hacer lo mismo."}], "id": "CVE-2025-39841", "lastModified": "2026-10-19T21:10:00.160", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 9.8, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 3.9, "impactScore": 5.9, "source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 7.8, "baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 5.9, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2025-39841", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "timestamp": "2026-06-10T20:42:00.721283Z", "version": "2.0.3"}}]}, "published": "2025-09-19T16:15:42.813", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/367cb5ffd8a8a4c85dc89f55e7fa7cc191425b11"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/55658c7501467ca9ef3bd4453dd920010db8bc13"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/897f64b01c1249ac730329b83f4f40bab71e86c7"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/95b63d15fce5c54a73bbf195e1aacb5a75b128e2"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/9dba9a45c348e8460da97c450cddf70b2056deb3"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ab34084f42ee06a9028d67c78feafb911d33d111"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/baa39f6ad79d372a6ce0aa639fbb2f1578479f57"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/d96cc9a1b57725930c60b607423759d563b4d900"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Mailing List", "Third Party Advisory"], "url": "https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Mailing List", "Third Party Advisory"], "url": "https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"}, {"source": "0b142b55-0307-4c5a-b3c9-f314f3fb7c5e", "url": "https://cert-portal.siemens.com/productcert/html/ssa-032379.html"}, {"source": "0b142b55-0307-4c5a-b3c9-f314f3fb7c5e", "url": "https://cert-portal.siemens.com/productcert/html/ssa-089022.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-787"}], "source": "nvd@nist.gov", "type": "Primary"}]}
