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

  - perf/core: Prevent VMA split of buffer mappings The perf mmap code is careful about mmap()'ing the user     page with the ringbuffer and additionally the auxiliary buffer, when the event supports it. Once the first     mapping is established, subsequent mapping have to use the same offset and the same size in both cases.
    The reference counting for the ringbuffer and the auxiliary buffer depends on this being correct. Though     perf does not prevent that a related mapping is split via mmap(2), munmap(2) or mremap(2). A split of a     VMA results in perf_mmap_open() calls, which take reference counts, but then the subsequent     perf_mmap_close() calls are not longer fulfilling the offset and size checks. This leads to reference     count leaks. As perf already has the requirement for subsequent mappings to match the initial mapping, the     obvious consequence is that VMA splits, caused by resizing of a mapping or partial unmapping, have to be     prevented. Implement the vm_operations_struct::may_split() callback and return unconditionally -EINVAL.
    That ensures that the mapping offsets and sizes cannot be changed after the fact. Remapping to a different     fixed address with the same size is still possible as it takes the references for the new mapping and     drops those of the old mapping. (CVE-2025-38563)

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