 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:usb: xhci: Apply the link chain quirk on NEC isoc endpointsTwo clearly different specimens of NEC uPD720200 (one with start/stopbug, one without) were seen to cause IOMMU faults after some MissedService Errors. Faulting address is immediately after a transfer ringsegment and patched dynamic debug messages revealed that the MSE wasreceived when waiting for a TD near the end of that segment:[ 1.041954] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ffa08fe0[ 1.042120] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09000 flags=0x0000][ 1.042146] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09040 flags=0x0000]It gets even funnier if the next page is a ring segment accessible tothe HC. Below, it reports MSE in segment at ff1e8000, plows through azero-filled page at ff1e9000 and starts reporting events for TRBs inpage at ff1ea000 every microframe, instead of jumping to seg ff1e6000.[ 7.041671] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ff1e8fe0[ 7.041999] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ff1e8fe0[ 7.042011] xhci_hcd: WARN: buffer overrun event for slot 1 ep 2 on endpoint[ 7.042028] xhci_hcd: All TDs skipped for slot 1 ep 2.

Was itcaused by the above? I don t know, but it may have been. The diskwas working without any other issues and generated PCIe traffic tostarve the NEC of upstream BW and trigger those MSEs.
