Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to an overflow in the blk ioctl discard() function when the start + len parameter exceeds the maximum allowed value. This can cause a hung task if a discard ioctl is submitted with specific parameters, such as start = 0x80000000000ff000 and len = 0x8000000000fff000. The problem has been resolved by adding overflow validation.
