In the Linux kernel, the following vulnerability has been resolved: nvme: add missing SRCU grace period in error path nvme_alloc_ns() error path at out_unlink_ns removes ns from the namespace head siblings list with list_del_rcu(&ns->siblings) but does not wait for SRCU readers before freeing the namespace struct. Multipath code iterates the head->list under srcu_read_lock() in nvme_find_path() and nvme_mpath_revalidate_paths(), so a concurrent reader can still hold a reference to ns when kfree(ns) runs. The normal removal path in nvme_ns_remove() correctly calls synchronize_srcu(&ns->head->srcu) after list_del_rcu() to wait for in-progress readers. Add the same grace period in the error path.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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.

  - nvme: add missing SRCU grace period in error path nvme_alloc_ns() error path at out_unlink_ns removes ns     from the namespace head siblings list with list_del_rcu(&ns->siblings) but does not wait for SRCU readers     before freeing the namespace struct. Multipath code iterates the head->list under srcu_read_lock() in     nvme_find_path() and nvme_mpath_revalidate_paths(), so a concurrent reader can still hold a reference to     ns when kfree(ns) runs. The normal removal path in nvme_ns_remove() correctly calls     synchronize_srcu(&ns->head->srcu) after list_del_rcu() to wait for in-progress readers. Add the same grace     period in the error path. (CVE-2026-89972)

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