Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:4057 advisory.

 The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

 Security Fix(es):

 * Kernel: page cache side channel attacks (CVE-2019-5489)

 * kernel: Handling of might_cancel queueing is not properly pretected against race (CVE-2017-10661)

 * kernel: Inifinite loop vulnerability in mm/madvise.c:madvise_willneed() function allows local denial of service (CVE-2017-18208)

 * kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c (CVE-2019-11811)

 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):

 * update the MRG 2.5.z 3.10 realtime-kernel sources (BZ#1765670)

 * [MRG/R] pip_stress hangs when a priority inversion occurs (BZ#1772562)

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-rt package based on the guidance in RHSA-2019:4057.
