Then the probe fails without\ndisabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL.\n\nRather fix the error path: disable all the low level hardware in the\nerror path, by using the \"hsotg->ll_hw_enabled\" flag. Checking dr_mode\nhas been introduced to avoid a dual call to dwc2_lowlevel_hw_disable().\n\"ll_hw_enabled\" should achieve the same (and is used currently in the\nremove() routine)."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: dwc2: se corrige una fuga de devres en hw_enable al reanudar la suspensión. Cada vez que la plataforma pasa a bajo consumo, las rutinas de suspensión/reinicio de PM llaman a __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset(). Esto agrega un nuevo devres cada vez. Esto también puede ocurrir en tiempo de ejecución, ya que dwc2_lowlevel_hw_enable() puede llamarse desde udc_start(). Esto se puede ver con el seguimiento: - echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable - ir a bajo consumo - cat /sys/kernel/debug/tracing/trace Se encuentra una nueva entrada \"ADD\" en cada ciclo de bajo consumo: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... Aquí se aborda un segundo problema: - regulator_bulk_enable() se llama en cada ciclo de PM (suspender/reanudar). - regulator_bulk_disable() nunca se llama. Por lo tanto, el recuento de referencias para estos reguladores aumenta constantemente, en uno con cada ciclo de bajo consumo, debido a la falta de la llamada a regulator_bulk_disable() en __dwc2_lowlevel_hw_disable(). La corrección original, que introdujo la llamada a devm_add_action_or_reset(), solucionó un problema durante el sondeo que se produce debido a otros errores en dwc2_driver_probe() -> dwc2_core_reset(). En ese caso, el sondeo falla sin deshabilitar los reguladores cuando dr_mode == USB_DR_MODE_PERIPHERAL. Mejor solución: deshabilite todo el hardware de bajo nivel en la ruta de error mediante el indicador \"hsotg->ll_hw_enabled\". Se ha introducido la comprobación de dr_mode para evitar una llamada dual a dwc2_lowlevel_hw_disable(). \"ll_hw_enabled\" debería lograr el mismo efecto (y se utiliza actualmente en la rutina remove())."}],"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-401"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4.233","versionEndExcluding":"4.5","matchCriteriaId":"8B4E143B-22A3-4A08-963A-D5E42624F2E9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.9.233","versionEndExcluding":"4.10","matchCriteriaId":"5CABC2BE-6BAD-4283-89B2-D98A50976680"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.14.194","versionEndExcluding":"4.15","matchCriteriaId":"754AC47E-9FCE-4357-9717-F625B68662FB"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19.140","versionEndExcluding":"4.20","matchCriteriaId":"672D57CA-6B11-4A62-A86A-7E310B74C321"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4.59","versionEndExcluding":"5.5","matchCriteriaId":"FAC905ED-E26D-4E98-9EA6-F9162C3B259C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.7.16","versionEndExcluding":"5.8","matchCriteriaId":"ED553EDD-0029-44FB-ABF4-87D601D3D1AD"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8.2","versionEndExcluding":"5.10.177","matchCriteriaId":"214C9267-488A-4796-A952-350A69F24905"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.105","matchCriteriaId":"0888AE70-CB0A-45C0-B9BD-A5371244C8DB"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.22","matchCriteriaId":"642B6F99-95C6-47F5-A9B1-5C45FE08CAD0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.2.9","matchCriteriaId":"914F22DD-1E6F-4B0A-A14D-3A9F068F6761"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.3:rc1:*:*:*:*:*:*","matchCriteriaId":"B8E3B0E8-FA27-4305-87BB-AF6C25B160CB"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.3:rc2:*:*:*:*:*:*","matchCriteriaId":"A47F0FC3-CE52-4BA1-BA51-22F783938431"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.3:rc3:*:*:*:*:*:*","matchCriteriaId":"3583026A-27EC-4A4C-850A-83F2AF970673"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/1f01027c51eb16145e8e07fafea3ca07ef102d06","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/6485fc381b6528b6f547ee1ff10bdbcbe31a6e4c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/cba76e1fb896b573f09f51aa299223276a77bc90","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/f747313249b74f323ddf841a9c8db14d989f296a","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ffb8ab6f87bd28d700ab5c20d9d3a7e75067630d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
