Unity Linux 20.1050a Security Update: kernel (UTSA-2026-098724)

medium Nessus Plugin ID 340274

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098724 advisory.

In the Linux kernel, the following vulnerability has been resolved:

crypto: seqiv - Do not use req->iv after crypto_aead_encrypt

As soon as crypto_aead_encrypt is called, the underlying request may be freed by an asynchronous completion. Thus dereferencing req->iv after it returns is invalid.

Instead of checking req->iv against info, create a new variable unaligned_info and use it for that purpose instead.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
