In the Linux kernel, the following vulnerability has been resolved:

usb: usbtmc: Flush anchored URBs in usbtmc_release

When calling usbtmc_release, pending anchored URBs must be flushed or killed to prevent use-after-free errors (e.g. in the HCD giveback path). Call usbtmc_draw_down() to allow anchored URBs to be completed.
