  "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.",
