This is due to fact that the Thunderbolt networking driver\nalso tries to cleanup the paths and ends up blocking in\ntb_disconnect_xdomain_paths() waiting for the domain lock.\n\nHowever, at this point we already cleaned the paths in tb_stop() so\nthere is really no need for tb_disconnect_xdomain_paths() to do that\nanymore. Furthermore it already checks if the XDomain is unplugged and\nbails out early so take advantage of that and mark the XDomain as\nunplugged when we remove the parent router."}, {"lang": "es", "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: thunderbolt: marcar XDomain como desconectado cuando se quita el enrutador Not\u00e9 que cuando hacemos una actualizaci\u00f3n NVM del enrutador de host discreto y se elimina en caliente del lado PCIe como resultado de la autenticaci\u00f3n del firmware NVM, si hay otro host conectado con rutas habilitadas, nos quedamos sin desmantelarlos. Esto se debe al hecho de que el controlador de red Thunderbolt tambi\u00e9n intenta limpiar las rutas y termina bloqueando en tb_disconnect_xdomain_paths() esperando el bloqueo del dominio. Sin embargo, en este punto ya limpiamos las rutas en tb_stop(), por lo que realmente no hay necesidad de que tb_disconnect_xdomain_paths() haga eso m\u00e1s. Adem\u00e1s, ya verifica si el XDomain est\u00e1 desconectado y se retira temprano, as\u00ed que aproveche eso y marque el XDomain como desconectado cuando eliminemos el enrutador principal."}], "lastModified": "2024-09-19T13:35:58.637", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8F0D241D-4DAA-47F2-A87F-FBB28B3DA898", "versionEndExcluding": "5.10.225"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "913ED6CD-8ACF-48AF-AA18-7880881DD402", "versionEndExcluding": "5.15.166", "versionStartIncluding": "5.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "53954FF8-CB48-4302-BC4C-9DA7A88F44A2", "versionEndExcluding": "6.1.107", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9DE9201A-CE6B-4726-BABB-8265EA0F8AE4", "versionEndExcluding": "6.6.48", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D2AFDFD1-D95A-4EB7-843B-5E7659518B67", "versionEndExcluding": "6.10.7", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8B3CE743-2126-47A3-8B7C-822B502CF119"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4DEB27E7-30AA-45CC-8934-B89263EF3551"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.11:rc3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E0005AEF-856E-47EB-BFE4-90C46899394D"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
