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" } ] } ] } }
