kernel: Linux kernel: Integer overflow in iwlwifi debugfs function

A flaw was identified in the Linux kernel’s iwlwifi PCIe driver. In the function iwlwritetouserbuf—which is invoked by iwldbgfsmonitordataread—an attacker could supply a specially crafted count value e.g., SIZEMAX. This leads to an integer overflow when calculating the remaining buffer space,...
