La devoluci\u00f3n de llamada queue_response puede volver a encolar y volver a enviar la misma solicitud\n4. El reenv\u00edo reutiliza el mismo inline_bio de nvmet_req\n5. Mientras tanto, nvmet_req_bio_put() (llamada despu\u00e9s de nvmet_req_complete) invoca bio_uninit() para inline_bio, lo que establece bio->bi_blkg en NULL\n6. El bio reenviado entra en submit_bio_noacct_nocheck()\n7. blk_cgroup_bio_start() desreferencia bio->bi_blkg, causando un fallo:\n\n ERROR: desreferencia de puntero NULL del kernel, direcci\u00f3n: 0000000000000028\n #PF: acceso de lectura de supervisor en modo kernel\n RIP: 0010:blk_cgroup_bio_start+0x10/0xd0\n Rastro de Llamada:\n submit_bio_noacct_nocheck+0x44/0x250\n nvmet_bdev_execute_rw+0x254/0x370 [nvmet]\n process_one_work+0x193/0x3c0\n worker_thread+0x281/0x3a0\n\nCorregir esto reordenando nvmet_bio_done() para llamar a nvmet_req_bio_put() ANTES de nvmet_req_complete(). Esto asegura que el bio se limpie antes de que la solicitud pueda ser reenviada, previniendo la condici\u00f3n de carrera."}], "id": "CVE-2026-23148", "lastModified": "2026-10-19T19:17:39.533", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 3.9, "impactScore": 3.6, "source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "type": "Secondary"}, {"cvssData": {"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, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-23148", "options": [{"exploitation": "none"}, {"automatable": "yes"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-10-16T15:06:34.978751Z", "version": "2.0.3"}}]}, "published": "2026-02-14T16:15:54.913", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/0fcee2cfc4b2e16e62ff8e0cc2cd8dd24efad65e"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/68207ceefd71cc74ce4e983fa9bd10c3122e349b"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/ee10b06980acca1d46e0fa36d6fb4a9578eab6e4"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-476"}], "source": "nvd@nist.gov", "type": "Primary"}, {"description": [{"lang": "en", "value": "CWE-362"}], "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "type": "Secondary"}]}
