In the Linux kernel, the following vulnerability has been resolved:

crypto: algif aead - Revert to operating out-of-place

This mostly reverts commit 72548b093ee3 except for the copying of the associated data.

There is no benefit in operating in-place in algif aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.
