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: ARC: mm: fix leakage of memory     allocated for PTE Since commit d9820ff (ARC: mm: switch pgtable_t back to struct page *) a memory     leakage problem occurs. Memory allocated for page table entries not released during process termination.
    This issue can be reproduced by a small program that allocates a large amount of memory. After several     runs, you'll see that the amount of free memory has reduced and will continue to reduce after each run.
    All ARC CPUs are effected by this issue. The issue was introduced since the kernel stable release     v5.15-rc1. As described in commit d9820ff after switch pgtable_t back to struct page *, a pointer to     struct page and appropriate functions are used to allocate and free a memory page for PTEs, but the     pmd_pgtable macro hasn't changed and returns the direct virtual address from the PMD (PGD) entry. Than     this address used as a parameter in the __pte_free() and as a result this function couldn't release memory     page allocated for PTEs. Fix this issue by changing the pmd_pgtable macro and returning pointer to struct     page. (CVE-2022-50446)

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