In the Linux kernel, the following vulnerability has been resolved:
block: fix overflow in blk_ioctl_discard()
There is no check for overflow of 'start + len' in blk_ioctl_discard().
Hung task occurs if submit an discard ioctl with the following param:
start = 0x80000000000ff000, len = 0x8000000000fff000;
Add the overflow validation now.
