Connect\n   =======\n->dwc3_thread_interrupt\n ->dwc3_ep0_interrupt\n  ->configfs_composite_setup\n   ->composite_setup\n    ->usb_ep_queue\n     ->dwc3_gadget_ep0_queue\n      ->__dwc3_gadget_ep0_queue\n       ->__dwc3_ep0_do_control_data\n        ->dwc3_send_gadget_ep_cmd\n\n2. Disconnect\n   ==========\n->dwc3_thread_interrupt\n ->dwc3_gadget_disconnect_interrupt\n  ->dwc3_ep0_reset_state\n   ->dwc3_ep0_end_control_data\n    ->dwc3_send_gadget_ep_cmd\n\nIn the issue scenario, in Exynos platforms, we observed that control\ntransfers for the previous connect have not yet been completed and end\ntransfer command sent as a part of the disconnect sequence and\nprocessing of USB_ENDPOINT_HALT feature request from the host timeout.\nThis maybe an expected scenario since the controller is processing EP\ncommands sent as a part of the previous connect. It maybe better to\nremove WARN_ON in all places where device endpoint commands are sent to\navoid unnecessary kernel panic due to warn."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/dwc3/ep0.c","drivers/usb/dwc3/gadget.c"],"versions":[{"version":"72246da40f3719af3bfd104a2365b32537c27d83","lessThan":"dfe40159eec6ca63b40133bfa783eee2e3ed829f","status":"affected","versionType":"git"},{"version":"72246da40f3719af3bfd104a2365b32537c27d83","lessThan":"5a1a847d841505dba2bd85602daf5c218e1d85b8","status":"affected","versionType":"git"},{"version":"72246da40f3719af3bfd104a2365b32537c27d83","lessThan":"84c95dbf5bece56086cdb65a64162af35158bdd9","status":"affected","versionType":"git"},{"version":"72246da40f3719af3bfd104a2365b32537c27d83","lessThan":"f49697dfba2915a9ff36f94604eb76fa61413929","status":"affected","versionType":"git"},{"version":"72246da40f3719af3bfd104a2365b32537c27d83","lessThan":"db27482b9db340402e05d4e9b75352bbaca51af2","status":"affected","versionType":"git"},{"version":"72246da40f3719af3bfd104a2365b32537c27d83","lessThan":"45eae113dccaf8e502090ecf5b3d9e9b805add6f","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/dwc3/ep0.c","drivers/usb/dwc3/gadget.c"],"versions":[{"version":"3.2","status":"affected"},{"version":"0","lessThan":"3.2","status":"unaffected","versionType":"semver"},{"version":"5.15.190","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.149","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.103","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.44","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.16.4","lessThanOrEqual":"6.16.*","status":"unaffected","versionType":"semver"},{"version":"6.17","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"5.15.190"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.1.149"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.6.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.12.44"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.16.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.2","versionEndExcluding":"6.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/dfe40159eec6ca63b40133bfa783eee2e3ed829f"},{"url":"https://git.kernel.org/stable/c/5a1a847d841505dba2bd85602daf5c218e1d85b8"},{"url":"https://git.kernel.org/stable/c/84c95dbf5bece56086cdb65a64162af35158bdd9"},{"url":"https://git.kernel.org/stable/c/f49697dfba2915a9ff36f94604eb76fa61413929"},{"url":"https://git.kernel.org/stable/c/db27482b9db340402e05d4e9b75352bbaca51af2"},{"url":"https://git.kernel.org/stable/c/45eae113dccaf8e502090ecf5b3d9e9b805add6f"}],"title":"usb: dwc3: Remove WARN_ON for device endpoint command timeouts","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T17:43:31.805Z"}},{"x_adpType":"supplier","providerMetadata":{"orgId":"0b142b55-0307-4c5a-b3c9-f314f3fb7c5e","shortName":"siemens-SADP","dateUpdated":"2026-05-12T12:07:10.119Z"},"affected":[{"vendor":"Siemens","product":"SIMATIC CN 4100","versions":[{"status":"affected","version":"0","lessThan":"V5.0","versionType":"custom"}],"defaultStatus":"unknown"}],"references":[{"url":"https://cert-portal.siemens.com/productcert/html/ssa-032379.html"}]}]}}
