Unity Linux 20.1070e Security Update: kernel (UTSA-2026-005526)

medium Nessus Plugin ID 300339

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-2026-005526 advisory.

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

 nfsd: call cache_put if xdr_reserve_space returns NULL

 If not enough buffer space available, but idmap_lookup has triggered lookup_fn which calls cache_get and returns successfully. Then we missed to call cache_put here which pairs with cache_get.

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.
