Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-07-14 15:31

Details

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,

Severity
7.8 (High)
