Critical Nessus Plugin ID 133508

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: 7.4

Synopsis

This plugin has been deprecated.

Description

An update for kernel-rt is now available for Red Hat Enterprise Linux 7.

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: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver (CVE-2019-14816)

* kernel: heap-based buffer overflow in mwifiex_process_country_ie() function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c (CVE-2019-14895)

* kernel: heap overflow in marvell/mwifiex/tdls.c (CVE-2019-14901)

* kernel: buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/ wext-sme.c (CVE-2019-17133)

* kernel: incomplete fix for race condition between mmget_not_zero()/ get_task_mm() and core dumping in CVE-2019-11599 (CVE-2019-14898)

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) :

* patchset for x86/atomic: Fix smp_mb__{before,after}_atomic() [kernel-rt] (BZ#1772522)

* kernel-rt: update to the RHEL7.7.z batch#4 source tree (BZ#1780322)

* kvm nx_huge_pages_recovery_ratio=0 is needed to meet KVM-RT low latency requirement (BZ#1781157)

* kernel-rt: hard lockup panic in during execution of CFS bandwidth period timer (BZ#1788057)

This plugin has been deprecated. Although RHSA-2020:0375 exists, it is for kernel-rt, which does not exist on CentOS. This CentOS copy of the advisory duplicates the CVEs and packages from the non-rt kernel in RHSA-2020:0374.
