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)

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.
