In the Linux kernel, the following vulnerability has been resolved: NFSD: Defer sub-object cleanup in export put callbacks svc_export_put() calls path_put() and auth_domain_put() immediately when the last reference drops, before the RCU grace period. RCU readers in e_show() and c_show() access both ex_path (via seq_path/d_path) and ex_client->name (via seq_escape) without holding a reference. If cache_clean removes the entry and drops the last reference concurrently, the sub-objects are freed while still in use, producing a NULL pointer dereference in d_path. Commit 2530766492ec ("nfsd: fix UAF when access ex_uuid or ex_stats") moved kfree of ex_uuid and ex_stats into the call_rcu callback, but left path_put() and auth_domain_put() running before the grace period because both may sleep and call_rcu callbacks execute in softirq context. Replace call_rcu/kfree_rcu with queue_rcu_work(), which defers the callback until after the RCU grace period and executes it in process context where sleeping is permitted. This allows path_put() and auth_domain_put() to be moved into the deferred callback alongside the other resource releases. Apply the same fix to expkey_put(), which has the identical pattern with ek_path and ek_client. A dedicated workqueue scopes the shutdown drain to only NFSD export release work items; flushing the shared system_unbound_wq would stall on unrelated work from other subsystems. nfsd_export_shutdown() uses rcu_barrier() followed by flush_workqueue() to ensure all deferred release callbacks complete before the export caches are destroyed.

    ice: Fix memory leak in ice_set_ringparam()(CVE-2026-23389)

Tenable has extracted the preceding description block directly from the EulerOS kernel 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: Defer sub-object cleanup in export put callbacks svc_export_put() calls path_put() and     auth_domain_put() immediately when the last reference drops, before the RCU grace period. RCU readers in     e_show() and c_show() access both ex_path (via seq_path/d_path) and ex_client->name (via seq_escape)     without holding a reference. If cache_clean removes the entry and drops the last reference concurrently,     the sub-objects are freed while still in use, producing a NULL pointer dereference in d_path. Commit     2530766492ec (nfsd: fix UAF when access ex_uuid or ex_stats) moved kfree of ex_uuid and ex_stats into     the call_rcu callback, but left path_put() and auth_domain_put() running before the grace period because     both may sleep and call_rcu callbacks execute in softirq context. Replace call_rcu/kfree_rcu with     queue_rcu_work(), which defers the callback until after the RCU grace period and executes it in process     context where sleeping is permitted. This allows path_put() and auth_domain_put() to be moved into the     deferred callback alongside the other resource releases. Apply the same fix to expkey_put(), which has the     identical pattern with ek_path and ek_client. A dedicated workqueue scopes the shutdown drain to only NFSD     export release work items; flushing the shared system_unbound_wq would stall on unrelated work from other     subsystems. nfsd_export_shutdown() uses rcu_barrier() followed by flush_workqueue() to ensure all deferred     release callbacks complete before the export caches are destroyed.

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