kernel: x86/fpu: Stop relying on userspace for info to fault in xsave buffer that cause loop forever

A flaw was found in the Linux kernel's x86/fpu module, which revolves around an issue with relying on user space for critical information regarding the xsave buffer. In the affected scenario, the expected size of the user space buffer is derived from user-controlled data, specifically,...
