Quentin Casasnovas 35a9ff4eec x86/microcode/intel: Handle truncated microcode images more robustly
We do not check the input data bounds containing the microcode before
copying a struct microcode_intel_header from it. A specially crafted
microcode could cause the kernel to read invalid memory and lead to a
denial-of-service.
