El controlador maestro I3C puede recibir una IBI de un dispositivo de destino que aún no se ha sondeado. En tales casos, el maestro llama a `i3c_master_queue_ibi()` para poner en cola una tarea de trabajo IBI, lo que genera el error \"No se puede manejar la lectura del kernel desde memoria ilegible\" y provoca un pánico del kernel. Flujo típico de manejo de IBI: 1. El maestro I3C escanea los dispositivos de destino y sondea sus respectivos controladores. 2. El controlador del dispositivo de destino llama a `i3c_device_request_ibi()` para habilitar IBI y asigna `dev->ibi = ibi`. 3. El maestro I3C recibe una IBI del dispositivo de destino y llama a `i3c_master_queue_ibi()` para poner en cola la tarea de manejo de IBI del controlador del dispositivo de destino. Sin embargo, dado que los eventos del dispositivo de destino son asíncronos a la secuencia de sondeo I3C, el paso 3 puede ocurrir antes del paso 2, lo que provoca que `dev->ibi` sea `NULL` y provoque un pánico del kernel. Agregue una comprobación de puntero NULL en `i3c_master_queue_ibi()` para evitar el acceso a un `dev->ibi` sin inicializar, garantizando así la estabilidad."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.0","versionEndExcluding":"5.4.293","matchCriteriaId":"D4DB5C27-62AD-452E-B39F-4C000E47B685"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.10.237","matchCriteriaId":"0710B81E-E2FA-4E15-8F68-D297EBB4D50D"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.181","matchCriteriaId":"12331C9E-F601-4EFC-899E-369F98DCC70B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.135","matchCriteriaId":"5B9ACE29-7445-4B6F-B761-6367C005E275"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.88","matchCriteriaId":"6E5947E5-45E3-462A-829B-382B3B1C61BD"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.12.24","matchCriteriaId":"1D35A8A8-F3EC-45E6-AD37-1F154B27529D"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.13.12","matchCriteriaId":"4A475784-BF3B-4514-81EE-49C8522FB24A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.14","versionEndExcluding":"6.14.3","matchCriteriaId":"483E2E15-2135-4EC6-AB64-16282C5EF704"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*","matchCriteriaId":"FA6FEEC2-9F11-4643-8827-749718254FED"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/09359e7c8751961937cb5fc50220969b0a4e1058","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/1b54faa5f47fa7c642179744aeff03f0810dc62e","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/3ba402610843d7d15c7f3966a461deeeaff7fba4","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/6871a676aa534e8f218279672e0445c725f81026","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/bd496a44f041da9ef3afe14d1d6193d460424e91","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/d83b0c03ef8fbea2f03029a1cc1f5041f0e1d47f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/e6bba328578feb58c614c11868c259b40484c5fa","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/fe4a4fc179b7898055555a11685915473588392e","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ff9d61db59bb27d16d3f872bff2620d50856b80c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List"]}]}}]}
