CVE-2026-43033

HighCVSS 7.8/10Last modified Oct 19, 2026

Description

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,
