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: kernel: be more careful about     dup_mmap() failures and uprobe registering If a memory allocation fails during dup_mmap(), the maple tree     can be left in an unsafe state for other iterators besides the exit path. All the locks are dropped before     the exit_mmap() call (in mm/mmap.c), but the incomplete mm_struct can be reached through (at least) the     rmap finding the vmas which have a pointer back to the mm_struct. Up to this point, there have been no     issues with being able to find an mm_struct that was only partially initialised. Syzbot was able to make     the incomplete mm_struct fail with recent forking changes, so it has been proven unsafe to use the     mm_struct that hasn't been initialised, as referenced in the link below. Although 8ac662f5da19f (fork:
    avoid inappropriate uprobe access to invalid mm) fixed the uprobe access, it does not completely remove     the race. This patch sets the MMF_OOM_SKIP to avoid the iteration of the vmas on the oom side (even though     this is extremely unlikely to be selected as an oom victim in the race window), and sets MMF_UNSTABLE to     avoid other potential users from using a partially initialised mm_struct. When registering vmas for     uprobe, skip the vmas in an mm that is marked unstable. Modifying a vma in an unstable mm may cause issues     if the mm isn't fully initialised. (CVE-2025-21709)

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