Por lo tanto, buscamos en las tablas de excepciones el nip que gener\u00f3 el fallo. Si hay una entrada, dejamos que el controlador de la tabla de correcciones se encargue del fallo de p\u00e1gina devolviendo un error desde dentro de ___do_page_fault(). Esto se puede activar f\u00e1cilmente si alguien intenta hacer dd desde /proc/kcore. p. ej. dd if=/proc/kcore of=/dev/null bs=1M Algunos ejemplos de falsos negativos: ================================ ERROR: KFENCE: lectura no v\u00e1lida en copy_from_kernel_nofault+0x9c/0x1a0 Lectura no v\u00e1lida en 0xc0000000fdff0000: copy_from_kernel_nofault+0x9c/0x1a0 0xc00000000665f950 read_kcore_iter+0x57c/0xa04 proc_reg_read_iter+0xe4/0x16c vfs_read+0x320/0x3ec ksys_read+0x90/0x154 system_call_exception+0x120/0x310 ERROR: KFENCE: lectura de use-after-free en copy_from_kernel_nofault+0x9c/0x1a0 Lectura de use-after-free en 0xc0000000fe050000 (en kfence-#2): copy_from_kernel_nofault+0x9c/0x1a0 0xc00000000665f950 read_kcore_iter+0x57c/0xa04 proc_reg_read_iter+0xe4/0x16c vfs_read+0x320/0x3ec ksys_read+0x90/0x154 system_call_exception+0x120/0x310 system_call_vectored_common+0x15c/0x2ec"}], "id": "CVE-2024-56678", "lastModified": "2025-03-24T17:32:09.777", "metrics": {"cvssMetricV31": [{"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": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}]}, "published": "2024-12-28T10:15:08.797", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/06dbbb4d5f7126b6307ab807cbf04ecfc459b933"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/15f78d2c3d1452645bd8b9da909b0ca266f83c43"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/4d2655754e94741b159aa807b72ea85518a65fd5"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/7eaeb7a49b6d16640f9f3c9074c05175d74c710b"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/9ea8d8bf9b625e8ad3be6b0432aecdc549914121"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/e0a470b5733c1fe068d5c58b0bb91ad539604bc6"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-416"}], "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}]}
