Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Real Time (v. 8) - x86_64 Red Hat Enterprise Linux Real Time for NFV (v. 8) - 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: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow (CVE-2019-17666) * kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS (CVE-2019-14814) * kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell WiFi driver leading to DoS (CVE-2019-14815) * kernel: incomplete fix for race condition between mmget_not_zero()/get_task_mm() and core dumping in CVE-2019-11599 (CVE-2019-14898) * Kernel: KVM: export MSR_IA32_TSX_CTRL to guest - incomplete fix for TAA (CVE-2019-11135) (CVE-2019-19338) 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): * kernel-rt: update RT source tree to the RHEL-8.1.z2 source tree (BZ#1780326) 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.
