medium Tenable Cloud Security Plugin ID 450470

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: af_unix: Fix data-race around
unix_tot_inflight. unix_tot_inflight is changed under spin_lock(unix_gc_lock), but unix_release_sock()
reads it locklessly. Let's use READ_ONCE() for unix_tot_inflight. Note that the writer side was marked by
commit 9d6d7f1cb67c ("af_unix: annote lockless accesses to unix_tot_inflight & gc_in_progress") BUG:
