In the Linux kernel, the following vulnerability has been resolved:
crypto: seqiv - Handle EBUSY correctly
As it is seqiv only handles the special return value of EINPROGERSS, which means that in all other cases it will free data related to the request.
However, as the caller of seqiv may specify MAY_BACKLOG, we also need to expect EBUSY and treat it in the same way. Otherwise backlogged requests will trigger a use-after-free.
