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: btrfs: ensure pages are unlocked on     cow_file_range() failure There is a hung_task report on zoned btrfs like below.

Also, we can reproduce the same symptom with an error injected     cow_file_range() setup. The hang occurs when cow_file_range() fails in the middle of allocation.
    cow_file_range() called from do_allocation_zoned() can split the give region ([start, end]) for allocation     depending on current block group usages. When btrfs can allocate bytes for one part of the split regions     but fails for the other region (e.g. because of -ENOSPC), we return the error leaving the pages in the     succeeded regions locked. Technically, this occurs only when @unlock == 0. Otherwise, we unlock the pages     in an allocated region after creating an ordered extent. Considering the callers of     cow_file_range(unlock=0) won't write out the pages, we can unlock the pages on error exit from     cow_file_range(). So, we can ensure all the pages except @locked_page are unlocked on error case. In     summary, cow_file_range now behaves like this: - page_started == 1 (return value) - All the pages are     unlocked. IO is started. - unlock == 1 - All the pages except @locked_page are unlocked in any case -     unlock == 0 - On success, all the pages are locked for writing out them - On failure, all the pages except     @locked_page are unlocked (CVE-2022-50089)

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