medium Nessus Plugin ID 308688
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-2026-011221 advisory.In the Linux kernel, the following vulnerability has been resolved:
crypto: essiv - Handle EBUSY correctly
As it is essiv only handles the special return value of EINPROGERSS, which means that in all other cases it will free data related to the request.
However, as the caller of essiv may specify MAY_BACKLOG, we also need to expect EBUSY and treat it in the same way. Otherwise backlogged requests will trigger a use-after-free.
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.See Also
