Summary
In the Linux kernel, the following vulnerability has been resolved: nvme: fix a possible use-after-free in controller reset during load Unlike .queue_rq, in .submit_async_event drivers may not check the ctrl readiness for AER submission. This may lead to a use-after-free condition that was observed with nvme-tcp. The race condition may happen in the following scenario: 1. driver executes its reset_ctrl_work 2. -> nvme_stop_ctrl - flushes ctrl async_event_work 3. ctrl sends AEN which is received by the host, which in turn schedules AEN handling 4. teardown admin queue (which releases the queue socket) 5. AEN processed, submits another AER, calling the driver to submit 6. driver attempts to send the cmd ==> use-after-free In order to fix that, add ctrl state check to validate the ctrl is actually able to accept the AER submission. This addresses the above race in controller resets because the driver during teardown should: 1. change ctrl state to RESETTING 2. flush async_event_work (as well as other async work elements) So after 1,2, any other AER command will find the ctrl state to be RESETTING and bail out without submitting the AER.

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\"]}]}}",
