In android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, in a qbt1000 ioctl handler, an incorrect buffer size check has an integer overflow vulnerability potentially leading to a buffer overflow.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
