      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: usbtmc: check URB actual_length for interrupt-IN notifications\n\nUSBTMC devices can use an optional interrupt endpoint for notification\nmessages. These typically contain two-byte headers indicating the\npayload format, but the driver does not check if these headers are\npresent before accessing the data buffers. In cases where the URB\nactual_length is not enough to fit these headers, the driver will either\ncause an out-of-bounds read, or consume stale leftover data from a\nprevious notification.\n\nFix by checking if actual_data contains enough bytes for the headers,\notherwise resubmit URB to the interrupt endpoint.",
