In the Linux kernel, the following vulnerability has been resolved:
dm-crypt: don’t modify the data when using authenticated encryption It was
said that authenticated encryption could produce invalid tag when the data
that is being encrypted is modified [1]. So, fix this problem by copying
the data into the clone bio first and then encrypt them inside the clone
bio. This may reduce performance, but it is needed to prevent the user from
corrupting the device by writing data with O_DIRECT and modifying them at
the same time. [1]
