platform can crash in rare circumstances. The AES-XTS algorithm is usually used for disk
encryption.
The AES-XTS cipher decryption implementation for 64 bit ARM platform will read past the end of the
ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g. 144 bytes or 1024
bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash which
results in a denial of service.
If an attacker can control the size and location of the ciphertext buffer being decrypted by an
application using AES-XTS on 64 bit ARM, the application is affected. This is fairly unlikely
making this issue a Low severity one.");
