Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the authencesn component of the crypto subsystem during out-of-place decryption (where source and destination are different). The system unnecessarily saves high-order sequence bits in the destination, although they could be re-copied from the source. This requires the data to be hashed to be rearranged accordingly.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
