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

  - In the Linux kernel, the following vulnerability has been resolved: s390/ism: add release function for     struct device According to device_release() in /drivers/base/core.c, a device without a release function     is a broken device and must be fixed. The current code directly frees the device after calling     device_add() without waiting for other kernel parts to release their references. Thus, a reference could     still be held to a struct device, e.g., by sysfs, leading to potential use-after-free issues if a proper     release function is not set. (CVE-2025-21856)

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