Description OSIDB Bzimport 2026-05-01 15:04:57 UTC
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,
