New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
Synopsis
The remote Red Hat host is missing one or more security updates.
Description
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
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: insufficient input validation in kernel mode driver in Intel i915 graphics leads to privilege escalation (CVE-2019-11085)
* kernel: DMA attack using peripheral devices (Thunderclap) (BZ#1690716)
* kernel: infinite loop in update_blocked_averages() in kernel/sched/fair.c leading to denial of service (CVE-2018-20784)
* kernel: a NULL pointer dereference in drivers/scsi/megaraid/ megaraid_sas_base.c leading to DoS (CVE-2019-11810)
* 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.
