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 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.
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: kernel: DAX hugepages not considered during mremap (CVE-2020-10757) * kernel: buffer overflow in mwifiex_cmd_append_vsie_tlv function in drivers/net/wireless/marvell/mwifiex/scan.c (CVE-2020-12653) * kernel: heap-based buffer overflow in mwifiex_ret_wmm_get_status function in drivers/net/wireless/marvell/mwifiex/wmm.c (CVE-2020-12654) * kernel: use-after-free caused by a malicious USB device in the drivers/hid/usbhid/hiddev.c driver (CVE-2019-19527) 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: provide infrastructure to support dual-signing of the kernel (foundation to help address CVE-2020-10713) (BZ#1837438) * kernel-rt: update to the latest RHEL7.8.z3 source tree (BZ#1848017)
