Synopsis
The remote Red Hat host is missing one or more security updates.Description
The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5220 advisory.- kernel: the copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check (CVE-2020-29368)
- kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012)
- kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)
- kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)
- kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
