    Action Type Old Value New Value
    Added Description In the Linux kernel, the following vulnerability has been resolved:

    net/rose: prevent integer overflows in rose_setsockopt()

    In case of possible unpredictably large arguments passed to
    rose_setsockopt() and multiplied by extra values on top of that,
    integer overflows may occur.

    Do the safest minimum and fix these issues by checking the
    contents of ‘opt’ and returning -EINVAL if they are too large. Also,
    switch to unsigned int and remove useless check for negative ‘opt’
    in ROSE_IDLE case.
