medium Nessus Plugin ID 163963

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5937 advisory.

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

Security Fix(es):

* Incomplete cleanup of multi-core shared buffers (aka SBDR) (CVE-2022-21123)

* Incomplete cleanup of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)

* Incomplete cleanup in specific special register write operations (aka DRPW) (CVE-2022-21166)

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):

* SolarFlare sfc spurious TX completion (BZ#1793280)

* Page allocation failure on cryptsetup open (BZ#2072970)

* The kernel-rt crashes where one task is indefinitely looping in __start_cfs_bandwidth() with the cfs_b->lock spinlock being held (BZ#2077346)

* While using PTimekeeper the qede driver produces excessive log messages (BZ#2080646)

* The kernel crashes due to a GPF happens in mutex_spin_on_owner(). The known RDMA/cma bug that was introduced with a patch from upstream commit 722c7b2bfead is the possible cause. (BZ#2085425)

* Running LTP testcase creat09 fails showing related to 'cve-2018-13405' (BZ#2089360)

* Crash when releasing inode which was on unmouted superblock (BZ#2096884)

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-2022:5937.
