CVE-2026-64350 usb: cdnsp: fix stream context array leak in cdnsp_alloc_stream_info()

In the Linux kernel, the following vulnerability has been resolved: usb: cdnsp: fix stream context array leak in cdnspallocstreaminfo cdnspallocstreaminfo allocates streaminfo-streamctxarray with cdnspallocstreamctx. If a later stream ring allocation or stream mapping update fails, the error path...

CVE-2026-64348

The CVE-2026-64348 issue in the Linux kernel affects EHCI/FOTG210 isochronous submits, where a staged usb_schedule (ehci_iso_sched) attached to urb->hcpriv could leak if usb_hcd_link_urb_to_ep() fails or the controller becomes inaccessible. The published fixes free the staged schedule from don...

CVE-2026-64345

The CVE-2026-64345 issue affects the Linux kernel USB gadget f_printer driver. printer_open() increments dev->kref even when an open fails with -EBUSY, causing a reference leak because VFS does not call ->release() for failed opens. The fix moves the kref_get() into the successful-open path...

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fprinter: take kref only for successful open printeropen returns -EBUSY when the character device is already open, but it increments dev-kref regardless of the return value. VFS does not call -release for a failed...

CVE-2026-64338

CVE-2026-64338 concerns the Linux kernel USB subsystem, specifically the uss720 driver. The issue arises when uss720_probe() registers a parport before reading the 1284 register used to detect Belkin F5U002 adapters. If get_1284_register() fails, the error path currently drops the driver private ...

CVE-2026-64337

CVE-2026-64338 USB: misc: uss720: unregister parport on probe failure

In the Linux kernel, the following vulnerability has been resolved: USB: misc: uss720: unregister parport on probe failure uss720probe registers a parport before reading the 1284 register used to detect unsupported Belkin F5U002 adapters. If get1284register fails, the error path drops the driver...

CVE-2026-64337

CVE-2026-64337 (Linux kernel): usb mtu3 flaw where mtu3_gadget_queue() maps the request before verifying QMU GPD space, causing a DMA mapping to remain active if mtu3_prepare_transfer() fails and the request isn’t linked. The fix unmaps the DMA on the failed queue path before returning. Documents...
