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

  - 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.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
