In the Linux kernel, the following vulnerability has been resolved: net: caif: fix memory leak in caif_device_notify In case of caif_enroll_dev() fail, allocated link_support won't be assigned to the corresponding structure. So simply free allocated pointer in case of error

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: net: caif: fix memory leak in     caif_device_notify In case of caif_enroll_dev() fail, allocated link_support won't be assigned to the     corresponding structure. So simply free allocated pointer in case of error (CVE-2021-47122)

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