Detail
Problem 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Realtime (v. 7) - noarch, x86_64 Red Hat Enterprise Linux for Real Time for NFV (v. 7) - noarch, x86_64 3. Description: 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) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1744149 - CVE-2019-14816 kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver 1771909 - CVE-2019-17133 kernel: buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c 1773519 - CVE-2019-14901 kernel: heap overflow in marvell/mwifiex/tdls.c 1774671 - CVE-2019-14898 kernel: incomplete fix for race condition between mmget_not_zero()/get_task_mm() and core dumping in CVE-2019-11599 1774870 - CVE-2019-14895 kernel: heap-based buffer overflow in mwifiex_process_country_ie() function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c 1781157 - kvm nx_huge_pages_recovery_ratio=0 is needed to meet KVM-RT low latency requirement [rhel-7.7.z] |
