* kernel: improper initialization of the flags member of the new pipe_buffer (CVE-2022-0847)

* kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

* kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

Tenable has extracted the preceding description block directly from the CIQ security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
