There is a potential integer overflow which can occur during the allocation of memory, during parsing of the I2C_RDWR option in the i2cdev_ioctl() routine. Below is the vulnerable code:
<snip> Yes, this was a bug, 11 months ago, all distros have had this fixed in their latest kernels for a long time now. There was previous discussions about this on the linux-kernel mailing list, so you weren't the first to find it by a long shot. Also, distros ship their /dev/i2c* nodes as accessable only as root, so again, this isn't really a problem. thanks, greg k-h
