Описание

In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - Do not place hiseq at end of dst for out-of-place decryption When decrypting data that is not in-place (src != dst), there is no need to save the high-order sequence bits in dst as it could simply be re-copied from the source. However, the data to be hashed need to be rearranged accordingly. Thanks,

A flaw was found in the Linux kernel's authencesn cryptographic module. When performing out-of-place decryption (where source and destination data buffers are different), the system incorrectly handles high-order sequence bits. This leads to improper data rearrangement before hashing, which could potentially affect the integrity of cryptographic operations.
