    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: usbtmc: Flush anchored URBs in usbtmc_release\n\nWhen calling usbtmc_release, pending anchored URBs must be flushed or\nkilled to prevent use-after-free errors (e.g. in the HCD giveback\npath). Call usbtmc_draw_down() to allow anchored URBs to be completed.",
