{"id":"CVE-2026-90030","summary":"usb: dwc3: clear forceRM when issuing EndTransfer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: dwc3: clear forceRM when issuing EndTransfer\n\nThe forceRM bit of the DEPCMD register controls the behavior of the\nEndTransfer command used to stop an active transfer. Older DWC3\nprogramming guide revisions recommended setting forceRM=1 when\nissuing EndTransfer. Newer programming guide revisions recommend\nissuing EndTransfer with forceRM cleared.\n\nWith forceRM=1 on DWC_usb31 v2.00a and v2.10a controllers, a transfer\naborted through the ep_dequeue path was observed to remain active\nafter EndTransfer completion. A subsequent StartTransfer issued on the\nsame endpoint triggered writes associated with the aborted transfer.\nThis resulted in an SMMU fault because the transfer buffer had already\nbeen unmapped during EndTransfer command-completion cleanup.\n\nUsing forceRM=0 eliminates the issue. Although older DWC3 programming\nguide revisions recommended setting forceRM=1, no issues are known\nfrom using forceRM=0. Clear forceRM when issuing EndTransfer to provide\nconsistent EndTransfer behavior and align with newer programming guide\nrecommendations.","modified":"2026-11-13T04:07:07.471245190Z","published":"2026-09-16T10:33:31.801Z","related":["SUSE-SU-2026:24550-1","SUSE-SU-2026:24619-1","SUSE-SU-2026:24643-1","SUSE-SU-2026:24648-1","SUSE-SU-2026:24651-1","SUSE-SU-2026:24662-1","SUSE-SU-2026:5091-1","openSUSE-SU-2026:11880-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90030.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0afe5c31612de3d18cc6d16e616da4a48ba1e5a2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a50e138fa28e5ba76b11af66ed41cc300c0f2be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f1e57c484f9edeaaa5a27a03ed985e98496e81d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b58e6200450d350314db0ecda7d6d1bde3281e80"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e01408ee52fe5cb2d0b43f47f359336af2b6c316"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90030.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90030"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ab99c4be945724b032cc55e05c6738fe1d84bf70"},{"fixed":"7a50e138fa28e5ba76b11af66ed41cc300c0f2be"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1e43c86d84fb0503e82a143e017f35421498fc1a"},{"fixed":"9f1e57c484f9edeaaa5a27a03ed985e98496e81d"},{"fixed":"0afe5c31612de3d18cc6d16e616da4a48ba1e5a2"},{"fixed":"e01408ee52fe5cb2d0b43f47f359336af2b6c316"},{"fixed":"b58e6200450d350314db0ecda7d6d1bde3281e80"}]}],"versions":["v6.6.159","v6.6.158","v6.6.157","v6.6.156","v6.6.155","v6.6.154","v6.6.153","v6.6.152","v6.6.151","v6.6.150","v6.6.149","v6.6.148","v6.6.147","v6.6.146","v6.6.145","v6.6.144","v6.6.143","v6.6.142","v6.6.141","v6.6.140","v6.6.139","v6.6.138","v6.6.137","v6.6.136","v6.6.135","v6.6.134","v6.6.133","v6.6.132","v6.6.131","v6.6.130","v6.6.129","v6.6.128","v6.6.127","v6.6.126","v6.6.125","v6.6.124","v6.6.123","v6.6.122","v6.6.121","v6.6.120","v6.6.119","v6.6.118","v6.6.117","v6.6.116","v6.6.115","v6.6.114","v6.6.113","v6.6.112","v6.6.111","v6.6.110","v6.6.109","v6.6.108","v6.6.107","v6.6.106","v6.6.105","v6.6.104","v6.6.103","v6.6.102","v6.6.101","v6.6.100","v6.6.99","v6.6.98","v6.6.97","v6.6.96","v6.6.95","v6.6.94","v6.6.93","v6.6.92","v6.6.91","v6.6.90","v6.6.89","v6.6.88","v6.6.87","v6.6.86","v6.6.85","v6.6.84","v6.6.83","v6.6.82","v6.6.81","v6.6.80","v6.6.79","v6.6.78","v6.6.77","v6.6.76","v6.6.75","v6.6.74","v6.6.73","v6.6.72","v6.6.71","v6.6.70","v6.6.69","v6.6.68","v6.6.67","v6.6.66","v6.6.65","v6.6.64","v6.6.63","v6.6.62","v6.6.61","v6.6.60","v6.6.59","v6.6.58","v6.6.57","v6.6.56","v6.6.55","v6.6.54","v6.6.53","v6.6.52","v6.6.51","v6.6.50","v6.6.49","v6.6.48","v6.6.47","v6.6.46","v6.6.45","v6.6.44","v6.6.43","v6.6.42","v6.6.41","v6.6.40","v6.6.39","v6.6.38","v6.6.37"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-90030.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.37"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-90030.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
