high Nessus Plugin ID 162652

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5249 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* 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-2022-1966)

* kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* make SHA512_arch algos and CRYPTO_USER built-ins (BZ#2072643)

* SR-IOV performance > 50% degradation (BZ#2074830)

* fix data corruption caused by dm-integrity (BZ#2082187)

* SCTP client-side peeloff issues [rhel-9] (BZ#2084044)

* TCP connection fails in a asymmetric routing situation (BZ#2085480)

* Fails to boot Multiple RT VMs each with multiple vCPUs (BZ#2086963)

* spec: Fix separate tools build (BZ#2090852)

* call traces related to eeh_pseries observed and vmcore is not captured, when kdump is triggered (BZ#2092255)

* Mark ThunderX NIC driver as unmaintained (BZ#2092638)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL kernel package based on the guidance in RHSA-2022:5249.
