In the Linux kernel, the following vulnerability has been resolved: nfsd: Fix cred ref leak in nfsd_nl_listener_set_doit(). nfsd_nl_listener_set_doit() uses get_current_cred() without put_cred(). As we can see from other callers, svc_xprt_create_from_sa() does not require the extra refcount. nfsd_nl_listener_set_doit() is always in the process context, sendmsg(), and current->cred does not go away. Let's use current_cred() in nfsd_nl_listener_set_doit().

The remote SUSE Linux SLES16 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:22099-1 advisory.

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - nfsd: Fix cred ref leak in nfsd_nl_listener_set_doit(). nfsd_nl_listener_set_doit() uses     get_current_cred() without put_cred(). As we can see from other callers, svc_xprt_create_from_sa() does     not require the extra refcount. nfsd_nl_listener_set_doit() is always in the process context, sendmsg(),     and current->cred does not go away. Let's use current_cred() in nfsd_nl_listener_set_doit().
    (CVE-2026-43394)

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1594 advisory.
