Capstone disassembles CD 00 0B 00 as a 32-bit instruction but it should be two 16-bit instructions. Note that, taken as a 32-bit instruction word, 0xCD000B00 is missing the leading three bits set required for a 4-byte wide encoding.

Here is minimal code for reproduction:

#!/usr/bin/env python
from capstone import *
md = Cs(CS_ARCH_ARM, CS_MODE_BIG_ENDIAN|CS_MODE_THUMB)
for i in md.disasm("\xCD\x00\x0b\x00", 0):
	print("0x%x:\t%s\t%s" %(i.address, i.mnemonic, i.op_str))

Which outputs vstr d0, [r0, #-0] when it should be ldmia r5!, {} and lsrs r0, r0, #12.
