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

  - gpio: virtuser: fix UAF in configfs release path The gpio-virtuser configfs release path uses guard(mutex)     to protect the device structure. However, the device is freed before the guard cleanup runs, causing     mutex_unlock() to operate on freed memory. Specifically, gpio_virtuser_device_config_group_release()     destroys the mutex and frees the device while still inside the guard(mutex) scope. When the function     returns, the guard cleanup invokes mutex_unlock(&dev->lock), resulting in a slab use-after-free. Limit the     mutex lifetime by using a scoped_guard() only around the activation check, so that the lock is released     before mutex_destroy() and kfree() are called. (CVE-2026-23158)

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