Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise MRG 2.
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.
Details
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: 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)
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):
* update the MRG 2.5.z 3.10 realtime-kernel sources (BZ#1810602)
