Affected files ============== The file(s) affected by this issue are: drivers/media/usb/uvc/uvc_queue.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/69c32df23bed6001864779b965fa009bcd9a26de https://git.kernel.org/stable/c/a5c01f15809d1d2c319d8bfb11d071df11ab731c https://git.kernel.org/stable/c/4cf3b6fd54ebb1ebc977bdc47fb6cfcf9a471a22
