Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel before 2.6.37 on platforms other than x86 allows local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
