A diferencia de .queue_rq, en .submit_async_event es posible que los controladores no verifiquen la preparaci\u00f3n de Ctrl para el env\u00edo de AER. Esto puede provocar una condici\u00f3n de use-after-free que se observ\u00f3 con nvme-tcp. La condici\u00f3n de ejecuci\u00f3n puede ocurrir en el siguiente escenario: 1. el controlador ejecuta su reset_ctrl_work 2. -\u0026gt; nvme_stop_ctrl - vac\u00eda ctrl async_event_work 3. ctrl env\u00eda AEN que es recibido por el host, que a su vez programa el manejo de AEN 4. desmontaje de la cola de administraci\u00f3n (que libera el socket de la cola) 5. AEN procesado, env\u00eda otro AER, llamando al controlador para enviar 6. el controlador intenta enviar el cmd ==\u0026gt; use-after-free Para solucionar eso, agregue la verificaci\u00f3n de estado de ctrl para validar que ctrl es realmente capaz de aceptar la presentaci\u00f3n de la ARE. Esto soluciona la ejecuci\u00f3n anterior en los reinicios del controlador porque el controlador durante el desmontaje debe: 1. cambiar el estado de Ctrl a RESTABLECER 2. vaciar async_event_work (as\u00ed como otros elementos de trabajo as\u00edncronos) Entonces, despu\u00e9s de 1,2, cualquier otro comando AER encontrar\u00e1 el estado de Ctrl estar RESETING y rescatar sin presentar la AER.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H\",\"baseScore\":7.0,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.0,\"impactScore\":5.9}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-416\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"4.19.231\",\"matchCriteriaId\":\"BED6719E-2004-42C8-8CA4-4E4CD159B63F\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.20\",\"versionEndExcluding\":\"5.4.181\",\"matchCriteriaId\":\"FB33213E-1A45-4E3B-A129-58AAA2EB921D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.102\",\"matchCriteriaId\":\"DAD66A9A-8D06-48D1-8AA8-FC060496FF53\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.25\",\"matchCriteriaId\":\"D098AA16-8E21-4EB7-AE2F-1EEB58E1A3A3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"5.16.11\",\"matchCriteriaId\":\"0D327234-5D4A-43DC-A6DF-BCA0CEBEC039\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/0ead57ceb21bbf15963b4874c2ac67143455382f\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/0fa0f99fc84e41057cbdd2efbfe91c6b2f47dd9d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/70356b756a58704e5c8818cb09da5854af87e765\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/9e956a2596ae276124ef0d96829c013dd0faf861\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/a25e460fbb0340488d119fb2e28fe3f829b7417e\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/e043fb5a0336ee74614e26f0d9f36f1f5bb6d606\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/0ead57ceb21bbf15963b4874c2ac67143455382f\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/0fa0f99fc84e41057cbdd2efbfe91c6b2f47dd9d\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/70356b756a58704e5c8818cb09da5854af87e765\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/9e956a2596ae276124ef0d96829c013dd0faf861\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/a25e460fbb0340488d119fb2e28fe3f829b7417e\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/e043fb5a0336ee74614e26f0d9f36f1f5bb6d606\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]}]}}"
