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: ALSA: timer: Don't take register_mutex     with copy_from/to_user() The infamous mmap_lock taken in copy_from/to_user() can be often problematic when     it's called inside another mutex, as they might lead to deadlocks. In the case of ALSA timer code, the bad     pattern is with guard(mutex)(ister_mutex) that covers copy_from/to_user() -- which was mistakenly     introduced at converting to guard(), and it had been carefully worked around in the past. This patch fixes     those pieces simply by moving copy_from/to_user() out of the register mutex lock again. (CVE-2025-23134)

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