CVE-2010-4157: Integer Overflow
First published: Mon Nov 08 2010(Updated: )
Description of problem: gdth_ioctl_alloc() takes the size variable as an int. copy_from_user() takes the size variable as an unsigned long. gen.data_len and gen.sense_len are unsigned longs. On x86_64 longs are 64 bit and ints are 32 bit. We could pass in a very large number and the allocation would truncate the size to 32 bits and allocate a small buffer. Then when we do the copy_from_user(), it would result in a memory corruption.
