high Nessus Plugin ID 168713

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-2022:8973 advisory.

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

Security Fix(es):

* kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region (CVE-2022-1158)

* kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)

* kernel: watch queue race condition can lead to privilege escalation (CVE-2022-2959)

* kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945)

* hw: cpu: incomplete clean-up of multi-core shared buffers (aka SBDR) (CVE-2022-21123)

* hw: cpu: incomplete clean-up of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)

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-2022:8973.
