RHEL 8 : kernel (RHSA-2022:5626)

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5626 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: cgroup: Use open-time creds and namespace for migration perm checks (CVE-2021-4197) - kernel: Race condition in races in sk_peer_pid and sk_peer_cred accesses (CVE-2021-4203) - 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: 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.
